IMAX (an acronym for Image MAXimum) is a motion picture film format and a set of cinema projection standards created by the Canadian company IMAX Corporation and developed by Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw.1 IMAX has the capacity to record and display images of far greater size and resolution than conventional film systems. Since 2002, some feature films have been converted (or upgraded) into IMAX format for display in IMAX theatres and some have also been partially shot in IMAX.

The desire to increase the visual impact of film has a long history. In 1929, Fox introduced Fox Grandeur, the first 70 mm film format, but it quickly fell from use.3 In the 1950s CinemaScope (1953) and VistaVision (1954) widened the image from 35 mm film, following multi-projector systems such as Cinerama (1952). While impressive, Cinerama was difficult to install.
During Expo 67 in Montreal, Kroitor's In the Labyrinth and Ferguson's Man and the Polar Regions both used multi-projector, multi-screen systems. Each encountered technical difficulties that led them to found a company, initially called "Multiscreen", with a primary goal of designing and developing a simpler approach. The single-projector/single-camera system they eventually settled upon was designed and built by Shaw based upon a novel "Rolling Loop" film-transport technology purchased from Peter Ronald Wright Jones, a machine shop worker from Brisbane Australia (see US Patent US3494524). As it became clear that a single, large-screen image had more impact than multiple smaller ones and was a more viable product direction, Multiscreen changed its name to IMAX.
Tiger Child, the first IMAX film, was demonstrated at Expo '70 in Osaka, Japan.4 The first permanent IMAX installation was built at the Cinesphere theatre at Ontario Place in Toronto. It debuted in May 1971, showing the film North of Superior. The installation is still in place,5 however, Ontario Place is on hiatus for redevelopment.
During Expo '74 in Spokane, Washington, an IMAX screen that measured 27 m × 20 m (89 ft × 66 ft) was featured in the US Pavilion (the largest structure in the expo). About five million visitors viewed the screen, which covered the viewer's total vision field when looking directly forward. This created a sensation of motion in most viewers, and motion sickness in some. An IMAX 3D theatre also is in operation near the former Expo 67 site at the Montreal Science Centre in the Port of Old Montreal.
The first permanent IMAX Dome installation, the Eugene Heikoff and Marilyn Jacobs Heikoff Dome Theatre at the Reuben H. Fleet Science Center, opened in San Diego's Balboa Park in 1973. It doubles as a planetarium. The first permanent IMAX 3D theatre was built in Vancouver, British Columbia for Transitions at Expo '86, and was in use until September 30, 2009.6 It was located at the tip of Canada Place, a Vancouver landmark.
The IMAX format in the USA has traditionally been employed for specialty applications. The expense and logistics of producing and presenting IMAX films has led to approximately 40 minute shorter running times than conventional films. The majority tend to be documentaries that are suited for institutional venues such as museums and science centers. IMAX cameras have orbited the earth, climbed Mount Everest, explored the bottom of the Atlantic Ocean, and visited the Antarctic. An IMAX documentary about the success of the Mars Exploration Rovers was released in 2006, titled Roving Mars and used exclusive data from the Rovers.8
One of the first attempts at presenting mainstream entertainment in the IMAX format was The Rolling Stones: Live at the Max (1991), an 85-minute compilation of concert footage filmed in IMAX during the band's 1990 Steel Wheels tour, edited to give the impression of a single concert.
In the 1990s more entertainment short films were created, notably T-Rex: Back to the Cretaceous in 1998 and Haunted Castle in 2001 (both in 3D). In 1995, French director Jean-Jacques Annaud directed Wings of Courage, the first dramatic picture shot for IMAX. In 1998 and '99, More and The Old Man and the Sea became the first short films produced using the IMAX format and both earned Academy Award nominations, with Old Man and the Sea winning (currently the only IMAX film to win an Oscar). In 2000, Disney produced Fantasia 2000, the first full-length animated feature initially released exclusively in the IMAX format.
IMAX increases the resolution of the image by using a much larger film frame: while a frame of 35mm film offers approximately six thousand lines (6K) of horizontal resolution, an IMAX negative can potentially display the equivalent of 18 thousand lines (18K) of horizontal resolution.9 To achieve this, 65 mm film stock passes horizontally through the camera, 15 perforations at a time resulting in a speed of 102.7 metres per minute. Traditional 65 mm cameras pass film vertically through the camera five perforations at a time resulting in a speed of 34 metres per minute. In comparison, 35 mm film runs vertically through the camera four perforations at a time, resulting in a speed of 27.4 metres per minute.9
Image area of 65 mm film is 48.5 mm × 22.1 mm (1.91 in × 0.87 in) (for Todd-AO), in IMAX the image is 69.6 mm × 48.5 mm (2.74 in × 1.91 in) tall. In order to match standard film speed of 24 frames per second, three times the length of film moves through the camera.
The IMAX format is generically called "15/70" film, the name referring to the 15 sprocket holes or perforations per frame. The film's bulk requires horizontal platters, rather than conventional film reels.10 IMAX platters range from 1.2 to 1.83 meters (3.9 to 6.0 ft) diameter to accommodate 1 to 2.75 hours of film. Platters with a 2.5 hour feature film weigh 250 kilograms (550 lb).
IMAX uses ESTAR-based print film11 in their 15/70 rolling-loop film projection systems. ESTAR-based print film provides greater precision. The chemical development process does not change the size or shape of ESTAR print film, and IMAX's pin registration system (especially the camera mechanism) does not tolerate either sprocket-hole or film-thickness variations.
In order to use more of the image area, IMAX film does not include an embedded soundtrack. Instead, the IMAX system specifies a separate six-channel 35 mm (1.377 inch) magnetic film, recorded and played back on a film follower locked to picture, just as Vitaphone had been (utilizing 16-inch 33 1/3 RPM electrical transcription discs) in the early 20th century, and was the same technology used to provide the 7-channel soundtrack accompanying films photographed and exhibited in the Cinerama process in the mid-1950s.
By the early 1990s, a separate DTS-based 6-track digital sound system was used, similarly locked to the projector by a SMPTE time code synchronization apparatus, the audio played off a series of proprietarily encoded CD-ROM discs. In the late 1990s this system was upgraded to one using a hard drive which carries a single uncompressed audio file containing the 6 channels. These are then converted directly to analogue rather than using a decoding method such as DTS.
Like conventional theatres, IMAX theatres place speakers both directly behind the acoustically transparent screen and around the theatre to create a "surround sound" effect. IMAX also provides a "top centre" speaker in addition to the centre speaker found in conventional theatres. This extra channel allows the sound mix engineers to take advantage of the screen's greater height.12
Drawing the large film through the projector presented challenges for both the camera and the projector. Conventional 70 mm systems were not steady enough for the 586× magnification. On the projector side, William Shaw adapted an Australian patent for film transport called the "rolling loop" by adding a compressed air "puffer" to accelerate the film, and put a cylindrical lens in the projector's "aperture block". The projector uses a vacuum to pull the film into contact with this lens. Thus the "field flattener" flattens the image field. The lens is twice the height of the film and connects to a pneumatic piston so it can be moved up or down while the projector is running. This way, if a piece of dust comes off the film and sticks to the lens, the projectionist can switch to the clean side of the lens at the push of a button. The lens also has "wiper bars" made of a felt or brush-like material which can wipe dust off the lens as it moves up or down. IMAX projectors are pin stabilized, meaning four registration pins engage the perforations at the corners of the projected frame to ensure perfect alignment. Shaw added cam-controlled arms to decelerate each frame to eliminate the microscopic shaking as the frame "settled" onto the registration pins. The projector's shutter is open around 20% longer than in conventional equipment and the light source is brighter. The xenon short-arc lamps are made of a thin layer of fused quartz and contain xenon gas at a pressure of about 25 atmospheres (367 PSI); because of this, projectionists are required to wear protective body armor when changing or handling these in case the lamp breaks (e.g., due to a drop to the floor) because of the danger from flying quartz shards when propelled by the high pressure of the xenon gas within. An IMAX projector weighs up to 1.8 tonne (2 short tons) and is over 178 cm (6 ft) tall and 195 cm (6 ft) long.
IMAX Corporation has released four projector types that use its 15-perforation, 70 mm film format: GT (Grand Theatre), GT 3D (dual rotor), SR (Small Rotor), and MPX, which was designed for retrofitted theatres.13 In July 2008, the company introduced a digital projection system, which it has not given a distinct name or brand, designed for multiplex theatres with screens no wider than 21.3 m (70 ft). All IMAX projectors, except the standard GT system, can project 3D images.
IMAX theatres are described as either "Classic Design" (purpose-built structures), or "Multiplex Design" (retrofitted auditoriums).8 Classic IMAX theatre construction differs significantly from conventional theatres. The increased resolution allows the audience to be much closer to the screen; typically all rows are within one screen height; conventional theatre seating runs 8 to 12 screen heights. Also, the rows of seats are set at a steep angle (up to 30° in some domed theatres) so that the audience is facing the screen directly.14
A standard IMAX screen is 22 m × 16.1 m (72 ft × 53 ft), but can be significantly larger. The world's largest IMAX screen is in Darling Harbour, Sydney, Australia, and measures 35.7 m x 29.7 m (117.1 ft x 97.4 ft).1516
In the late 1960s the San Diego Hall of Science (now known as the Reuben H. Fleet Science Center) began searching North America for a large-format film system to project on the dome of their planned 23.16 m (76.0 ft) tilted dome planetarium. The standard IMAX projector was unsuitable for use inside a dome because it had a 3.65 m (12.0 ft) tall lamp house on top. IMAX Corporation redesigned its system, adding an elevator to lift the projector to the center of the dome from the projection booth below. Spectra Physics designed a suitable lamphouse that took smaller, 46 cm (18 in) lamps and placed the bulb behind the lens instead of above the projector. In 1970,17 Ernst Leitz Canada, Ltd. (now ELCAN Optical Technologies) won a contract to develop and manufacture a fisheye lens projection system optimized to project an image onto a dome instead of a flat screen.
The dome system, which the San Diego Hall of Science called OMNIMAX, uses films shot with a camera equipped with a fisheye lens that squeezes a highly distorted 180° field of view onto the 65 mm IMAX film. The lens is aligned below the center of the frame and most of the bottom half of the circular field falls beyond the edge of the film. The part of the field that would fall below the edge of the dome is masked. When filming, the camera is aimed upward at an angle that matches the tilt of the dome. When projected through a matching fisheye lens onto a dome, the original panoramic view is recreated. OMNIMAX wraps 180° horizontally, 100° above the horizon and 22° below the horizon for a viewer at the center of the dome. OMNIMAX premiered in 1973 showing Voyage to the Outer Planets (produced by Graphic Films) and Garden Isle (by Roger Tilton Films) on a double bill.
IMAX has since renamed the system IMAX Dome. However, some theatres continue to call it OMNIMAX.
OMNIMAX theatres inhabit theme parks and North American museums, particularly those with a scientific focus, where the technical aspects of the system may be highlighted as part of the attraction. The projection room is often windowed to allow public viewing and accompanied by informational placards like other exhibits. The screen may be a permanent fixture, such as at the Museum of Science and Industry in Chicago, Illinois, Carnegie Science Center in Pittsburgh, Pennsylvania, the Franklin Institute in Philadelphia, Pennsylvania, the St. Louis Science Center, Boston's Museum of Science, Richmond's Science Museum of Virginia, Birmingham, Alabama's McWane Science Center and US Space and Rocket Center in Huntsville, AL and Great Lakes Science Center in Cleveland, OH; or lowered and raised as needed, such as at the Canadian Museum of History (where it shares an auditorium with a standard IMAX screen). The entire dome can be raised to show flat screen features and lowered for dome features. For the flat screen theaters, before the feature begins, the screen can be backlit to show the speakers and girders behind it. While the majority of museum installations focus on educational and documentary films, on special occasions, entertainment films are also shown, such as Charlie and the Chocolate Factory at the Oregon Museum of Science and Industry. The largest in North America are at Liberty Science Center in Jersey City, New Jersey and the Telus World of Science in Vancouver, BC, both of which have dome screens 27 metres (89 ft) in size.
To create the illusion of depth, the IMAX 3D process uses two separate camera lenses that represent the left and right eyes. The lenses are separated by a distance of 64 mm (2.5 in), the average distance between a human's eyes. Two separate rolls of film are used to capture the images they produce. The IMAX 3D camera weighs over 113 kg (249 lb).
By projecting the two films superimposed on the screen and using one of several available methods to direct only the correct image to each eye, viewers see a 3D image on a 2D screen.
One method is to use polarizing filters to oppositely polarize the light used in projecting each image. The viewer wears glasses with polarizing filters oriented to match the projector filters, so that the filter over each eye blocks the light used to project the images intended for the other eye.
In another method, the two projections rapidly alternate. While one image is being shown, the projection of its mate is blocked. Each frame is shown more than once to increase the rate and suppress flicker. The viewer wears shutter glasses with liquid crystal shutters that block or transmit light in sync with the projectors, so each eye sees only the images meant for it.
Variations on IMAX included the 48 frames per second IMAX HD process, which sought to produce smoother, more lifelike motion, while also reducing the blurring of moving objects, by doubling the normal film rate. The IMAX HD system was tested in 1992 at the Canada Pavilion of the Seville Expo '92 with the film Momentum.18 Higher production costs, and the high "wear-and-tear" on the prints and projectors, doomed the IMAX HD system, but, not before many theatres had been retrofitted to project at 48 frames, especially in Canada, in order to play Momentum.19 In the 1990s theme parks in Thailand, Germany, and Las Vegas used IMAX HD for their Motion Simulator rides.20 The Disney parks attraction Soarin' Over California features a modification of both IMAX HD and IMAX Dome, projecting in 48 frames per second.
The doubled IMAX HD frame rate means that each IMAX HD reel lasts half as long, and the logistical implications of this reach throughout the film production chain. IMAX production by default is at least 3 to 5 times more expensive than common 35mm production. The further increase in IMAX HD has prevented significant adoption.
Because 70mm film and projectors are costly and difficult to mass produce, IMAX debuted a digital projection system in 2008. It uses two projectors that can present either 2D or 3D content in DCI or IMAX Digital Format (IDF) (which in itself is a superset of DCI). As of 2012[update], IDF uses 2K-resolution Christie projectors with Texas Instruments' Digital Light Processing (DLP) technology alongside parts of IMAX's proprietary formats. The two 2K images are projected over each other to make the image brighter.
The digital installations have caused some controversy, as many theaters have branded their screens as IMAX after merely retrofitting standard auditoriums with IMAX digital projectors. The screen sizes in these auditoriums are much smaller than those in the purpose-built auditoriums of the original 15/70 IMAX format. These theaters charge the same premium pricing as the purpose-built IMAX theaters, resulting in consumer confusion.
Another disadvantage is the much lower resolution of digital IMAX compared to traditional IMAX film, which is estimated to be up to 8,700 lines of vertical resolution on the camera negative and 4,500 on a release print.21 Some reviewers also note that many non-IMAX theaters are already projecting films at 4K resolution, while digital IMAX has deployed both 2K and 4K products.
Despite these concerns, IMAX has consistently chosen to hold to a uniform marketing position of "The IMAX Experience" regardless of the various underlying technologies and screen sizes.22 Some high profile figures such as film critic Roger Ebert23 and others also actively voiced their concerns. On February 3, 2012, IMAX announced that it had selected Barco as the primary supplier of projectors for the next seven years.24 In late April 2012, IMAX began testing a new 4K laser-projection system, based on patents licensed from Eastman Kodak. Like the film and digital systems, it uses two projectors but it has been said to improve over the smaller digital screens by retaining the traditional IMAX aspect ratio and to allow films to be shown on screens 36 m (120 feet) wide or more. The laser projector will be available to exhibitors in the fourth quarter of 2013.25
IMAX has been moving forward with digital projection with success with The Hunger Games and The Avengers and the format has also aided in the company's worldwide growth, especially in Russia and China. Mainly because the system facilitates inexpensive distribution of IMAX features, the company has recently announced that they are re-renovating specially selected locations around the world to present both 70mm analog as well as digital presentations. To do so, IMAX has, with another, currently unknown, business partner, developed a rail system that allows the projectors to be moved in and out if there is either a full-frame film print available or a digital-only release. These theaters were prepared in time for the release of The Dark Knight Rises in July 2012.26
In 2011, IMAX announced a 4K 3D digital camera with the similar wide resolution of regular IMAX film cameras. The camera was developed alongside Vision Research and AbelCine, integrating two Phantom 65 engines. A prototype camera was used for the documentary Born to be Wild, in which approximately 10% of the finished film was shot with the system.27 It has been said that the company has no intention of replacing the higher resolution film cameras with the new digital camera, but the latter can be used in scenes that require a lightweight or relatively small 3D camera in order to film it without issue. Currently while IMAX has completed the production camera and has been placed into service on several films, there are no plans to produce an IMAX film using solely the new digital system. Transformers: Age of Extinction was partially filmed with the Phantom 65 IMAX 3D camera.28
Before the end of the 1990's, theatrical features were deemed impossible to run in the IMAX venues at the time, as there was a technical limitation on the size of the film reel where films had to be run around two hours. Originally IMAX and Pixar were considering re-releasing Toy Story in 3D, but the results of the tests displayed that the render resolution could not match to the size of the IMAX image.29 DreamWorks in the early 2000's wanted to re-release Shrek in IMAX 3D, but this too was canceled as a result of creative changes in the studio.30 These failed attempts at re-releases did inspire IMAX to experiment and improve their ability in presenting computer-animation in their theaters. Their compilation CyberWorld was the result, which contained new original animation and IMAX-presented versions of computer animated tests and music videos. Cyberworld even presented open-matte 3D versions of the bar sequence from Antz and the Homer3 segment from The Simpsons, both coincidentally were animated at Pacific Data Images.
Walt Disney Pictures became the first studio to release theatrical films in the IMAX process. Released on New Year's Day in 2000, Fantasia 2000 was the studio's first IMAX release and the first theatrical feature to be presented in IMAX theaters. It was originally planned as a standard theatrical release, but in agreeing with the company to release the film, the IMAX sound system incorporated a multi-channel and multi-layer stereo system for the orchestrated soundtrack, similar to the Fantasound system Walt Disney used for the original film decades ago. The company agreed to Disney's terms and conditions to gain the exclusive first showings of the film. These included a limited engagement of 4 months (from January 1 to April 30) and 50% of the box office receipts. Not all IMAX cinemas were prepared to accept Disney's terms to present the film; however, following the IMAX release, a standard 35mm run followed in June at regular theatres.
Although Fantasia 2000 had a luke-warm financial run, the critical praise for its use of the IMAX format convinced Disney to put more releases in the giant-screen format in the pipeline. In 2002, IMAX re-issues of Beauty and the Beast and The Lion King were released in select theaters over the winter and Christmas seasons of that year. New digital masters were created from the original CAPS production files and select scenes of animation were cleaned up to make use of the high resolution IMAX film negatives. Treasure Planet was also released in select IMAX theaters and was the first theatrical film to be released in regular and IMAX theaters simultaneously. But all of these releases had underwhelming box office returns and Disney canceled later big-screen re-releases, including Aladdin.
With the unveiling of the DMR process (see below), Warner Bros. Pictures especially embraced the format beginning in 2003 with the two Matrix sequels, Reloaded and Revolutions. Since The Prisoner of Azkaban in 2004, Warner Bros. began releasing the Harry Potter film franchise in IMAX to strong financial success. Also in 2004 the studio released Robert Zemeckis' motion-capture film The Polar Express in IMAX 3D. Polar Express became the most successful film to be released in IMAX theatres, producing at least a quarter of the film's gross of $302 million from fewer than 100 IMAX screens.citation needed Success for Warner Bros. and IMAX followed in later years with I Am Legend, Happy Feet, Batman Begins and The Dark Knight. Progressively other studios became further interested in releasing films in IMAX through the DMR process and have earned success through it. In 2009, J. J. Abrams' Star Trek was released for initially two weeks in IMAX venues in May and opened to $8.3 million dollars.31 The IMAX opening weekends of The Avengers and Harry Potter and the Deathly Hallows Part 2 have since grossed $15 million.
Though they weren't filmed with IMAX cameras, Skyfall and The Amazing Spider-Man were optimized for IMAX digital screens when they were released. Both movies were filmed in high-resolution cameras and the digital negative ratio was equal to that of the IMAX Digital frame. Skyfall increased the visual information of the entire film while Amazing Spider-Man optimized the finale battle with the Lizard. James Cameron's Titanic when it was restored and re-released in theaters also specially made an open-matte version for IMAX. In 2010 after years of successful IMAX DMR releases, Warner Bros. signed a deal to release up to 20 feature films in IMAX up to 2013, including educational documentaries that were in production.32 The deal is currently set to finish with the second part of The Hobbit in 2013.
IMAX's proprietary DMR (Digital Media Remastering) process allows conventional films to be upconverted into IMAX format. This special digital intermediate technology allowed films shot on 35mm for conventional theatres to be shown in IMAX venues. In 2002, Star Wars Episode II: Attack of the Clones and an IMAX-format re-release of the 1995 film Apollo 13, were the first official applications of the DMR process. Because of the projection limitations at the time, Apollo 13 and Attack of the Clones had to be edited down from their original length. As IMAX updated the system and expanded the size of the platters, the later DMR releases did not have this limitation; current platters allow a run time of up to 175 minutes.
Reviewers have generally praised the results of the DMR blowup process, which are visually and audibly superior to the same films projected in 35mm.citation needed But some filmmakers, such as producer Frank Marshall, point out that DMR blowups are not comparable to films created directly in the 70 mm 15 perf IMAX format, and that directors Ron Howard and George Lucas expected better.33 They note that the decline of Cinerama coincided roughly with its replacement by a simpler, cheaper, technically inferior version, and view DMR with alarm. IMAX originally reserved the phrase "the IMAX experience" for true 70 mm productions, but now allows its use on DMR productions as well.
After The Lion King in 2003, no Hollywood studio engaged in re-releasing and restoring classic films through the IMAX DMR process until 2012 although ongoing conversion of new releases continued and continued to grow in number. James Cameron's Titanic underwent both 3D conversion and DMR conversion to 3D in 2012 as did Men in Black 3. In August 2012 IMAX and Paramount Pictures announced a one-week exclusive re-release of Raiders of the Lost Ark on September 7, 2012, to promote the release of the Blu-Ray collection. The film, before it underwent DMR, was already restored in a 4K digital intermediate with 7.1 surround sound from the original negative. The process for IMAX theaters, like with the complete restoration, was supervised by Steven Spielberg and sound designer Ben Burtt. "I didn’t know if the 1981 print would stand up to a full IMAX transfer, so I came expecting a sort of grainy, muddy, and overly enlarged representation of the movie I had made years ago," Spielberg said. "I was blown away by the fact that it looked better than the movie I had made years ago." For other DMR releases and re-releases see List of IMAX DMR films.
Some recent features have employed IMAX cameras for select scenes, however no full-length feature film has yet been shot entirely using IMAX cameras due to the numerous difficulties presented with the format – the cameras are much larger and heavier than standard cameras and as they are noisier it makes dialogue recording difficult.34 The cameras have short film loads ranging from 30 seconds to two minutes34 and the cost of the film stock is much greater than standard 35mm film.35
The Dark Knight features six sequences (a total of 28 minutes) shot using IMAX. According to the film's press notes, this was the "first time ever that a major feature film has been even partially shot using IMAX cameras".36 Even before Dark Knight, Nolan had wanted to shoot a film in the IMAX format, and he also used it for quiet scenes which pictorially he thought would be interesting. Nolan said that he wished that it were possible to shoot the entire film in IMAX: "if you could take an IMAX camera to Mount Everest or outer space, you could use it in a feature movie." In addition, Nolan chose to edit some of the IMAX sequences using the original camera negative, which by eliminating generation loss, raised the film resolution of those sequences up to 18 thousand lines. When the film opened in 94 IMAX venues in 2008, all of them were sold out for the opening weekend.
A year later, director Michael Bay was inspired by IMAX's use in The Dark Knight to feature big-screen sequences in Transformers: Revenge of the Fallen.37 The film's co-writer Roberto Orci suggested that the IMAX footage would be 3D, but Bay later said that considering himself an "old school" filmmaker, he found 3D gimmicky and added that shooting in IMAX was easier than using stereoscopic cameras. The IMAX version of the film, in the end, contained almost ten minutes of IMAX-filmed footage out of the two and a half hour film. Bay later partially filmed the third Transformers film, Dark of the Moon in 3D but without IMAX. Bay returned to IMAX for the fourth film, Age of Extinction, in 2014. It will be the first feature film to be shot using digital IMAX 3D cameras.38
Two years later, Brad Bird's Mission: Impossible – Ghost Protocol had 25 minutes of footage shot using IMAX cameras.3940 Bird believed that using IMAX format would bring back "a level of showmanship" to the presentation of Hollywood films, which he believes the industry has lost due to its emphasis on screening films in multiplexes as opposed to grand theaters, and vetoing "first runs" in favor of wider initial releases.41 He also added that the IMAX format offered the viewer more immersion than digital 3D due to its brighter, higher quality image, which is projected on a larger screen, without the need for specialised glasses. Ghost Protocol opened on December 16, 2011, in almost 500 IMAX venues worldwide a week before its wide release where it earned third place in the box office and $12 million dollars.
Like with The Dark Knight, Christopher Nolan decided to film sequences of the sequel, The Dark Knight Rises, in 15/70mm IMAX.42 Nolan elected not to film in 3-D and stated that he intends to focus on improving image quality and scale using the IMAX format. In a Hollywood record, The Dark Knight Rises featured 72 minutes of footage shot in IMAX (in comparison, The Dark Knight contained 28 minutes.) But because of the considerable noise made by IMAX cameras, 35mm and 70mm cameras had to be used for shooting the film's dialogue scenes, and dialogue had to be dubbed when shot with IMAX cameras. Chairman and president of the IMAX Corporation Greg Foster stated that IMAX plans to run the film in its theaters for two months, despite only being contractually committed to run the film for two weeks in some theaters.
J. J. Abrams' Star Trek Into Darkness,43 Francis Lawrence's The Hunger Games: Catching Fire,44 Luc Besson's Lucy,45 and Christopher Nolan's Interstellar46 are recently released or upcoming films to have sequences filmed in IMAX.
On July 9, 2014, Bad Robot (JJ Abrams production company) confirmed via a picture uploaded to Twitter that select scenes in Disney & Lucasfilm's upcoming “Star Wars Episode VII” would be captured with the IMAX 15/70 perf film camera, in addition to the standard 35mm film cameras that Abrams and his cinematographer Dan Mindel have employed for shooting the movie.47
In 1996 IMAX was awarded the Oscar for Scientific and Technical Achievement by the Academy of Motion Picture Arts and Sciences.48 The award cited IMAX's innovations in creating and developing a method of filming and exhibiting large-format, wide-angle motion pictures.49
To date, ten native-format IMAX format films have received Academy Awards nomination, with one winner. While on technical aspects and the usage of the IMAX system, only Wally Pfister's cinematography on The Dark Knight has earned a nomination.
