Ultra Panavision 70

Ultra Panavision 70 and MGM Camera 65 were, from 1957 to 1966, the marketing brands that identified motion pictures photographed with Panavision's anamorphic movie camera lenses on 65 mm film. Ultra Panavision 70 and MGM Camera 65 were shot at 24 frames per second (fps) using anamorphic camera lenses. Ultra Panavision 70 and MGM Camera 65's anamorphic lenses compressed the image 1.25 times, yielding an extremely wide aspect ratio of 2.76:1 (when a 70 mm projection print was used).

Ultra Panavision saw much less use than its sibling, the more popular Super Panavision 70, and was only used on ten films from 1957 to 1966. However, nearly fifty years later, Robert Richardson famously resurrected Ultra Panavision 70 after the lens test he came to do at the Panavision headquarters for the upcoming project with Quentin Tarantino, where he discovered that the lenses and equipment were still intact. Tarantino was fascinated by this and was able to refurbish the lenses for use in his next film, The Hateful Eight; which was shot entirely on 65 mm film using Ultra Panavision lenses, the first film to do so since Khartoum. Tarantino also released the film as a roadshow release, and this was the first time there were widely circulated 70 mm film prints to theaters with 70 mm projectors since 1992's Far and Away. This ultimately led to a resurgence in the use of Ultra Panavision lenses, which have now been used (albeit with digital cameras) to shoot blockbusters such as Rogue One and Avengers: Endgame.

History
Metro-Goldwyn-Mayer (MGM) approached Panavision founder Robert Gottschalk in the late 1950s to create a large-format widescreen system capable of filling the extremely wide screens of Cinerama theaters while using a single projector, and would also be capable of producing high-quality standard 70 mm and 35 mm CinemaScope prints, which Cinerama's three-strip process did not allow for. Gottschalk developed a lens system using front-mounted prisms to impart a slight 1.25x squeeze onto a 5-perf 65 mm negative, resulting in a projected ratio of 2.76:1. These prism lenses were released under the name MGM Camera 65 in 1956.

In 1962, MGM's production of Mutiny on the Bounty, which was being produced in the format, ran far over-budget, and MGM was forced to sell off many of its assets to account for the losses. This allowed Panavision to purchase the Camera 65 equipment it had developed for MGM, and the system was renamed Ultra Panavision 70. As the prism lenses were bulky, oddly shaped and optically flawed, Panavision's optical engineer Takuo Miyagishima set to work on designing a more traditional set of 1.25x lenses using cylindrical glass, which became known as the Ultra Panatar series.

In 1963, the Cinerama Dome in Los Angeles became the first Cinerama theater built specifically for Ultra Panavision 70, and the theater opened with the premiere of It's a Mad, Mad, Mad, Mad World, which was filmed with the new Ultra Panatar lenses.

70 mm Ultra Panavision prints could be produced directly from the negative for use on flat screens, or "rectified" with increased compression towards the sides for use on curved Cinerama screens.

Panavision also developed a non-anamorphic 70 mm photographic system in 1959; this was named Super Panavision 70.

Differences from Todd-AO
The Ultra Panavision 70 and MGM Camera 65 lenses and cameras were similar to the 1955 version of the Todd-AO 65 mm photographic process, in that both were intended as replacements for three-strip Cinerama. The Todd-AO system was shot at 30 frames per second (fps), while Ultra Panavision 70 and MGM Camera 65 used the industry standard of 24 fps, and while the original Todd-AO process included the use of a deeply curved screen similar to that used for Cinerama (with fisheye optics to recreate its peripheral vision), its narrower, non-anamorphic 2.20:1 aspect ratio was incompatible with true Cinerama screens without cropping.

Films
The following films were shot in either MGM Camera 65 or Ultra Panavision 70: Many sources often claim the 1959 film The Big Fisherman was filmed in Ultra Panavision, but Panavision itself says that the film was shot in Super Panavision 70.
 * Raintree County (1957) – credited as MGM Camera 65 (exhibited in CinemaScope as all theaters that could project in Camera 65 were showing Michael Todd's Around the World in 80 Days).
 * Ben-Hur (1959) – credited as MGM Camera 65.
 * How the West Was Won (1962) – selected scenes only in Ultra Panavision.
 * The Wonderful World of the Brothers Grimm (1962) - selected scenes only in Ultra Panavision.
 * Mutiny on the Bounty (1962) – credited as Ultra Panavision.
 * It's a Mad, Mad, Mad, Mad World (1963) – filmed in Ultra Panavision. Also projected using the single-projector Cinerama system.
 * The Fall of the Roman Empire (1964) – credited as Ultra Panavision.
 * The Greatest Story Ever Told (1965) – filmed in Ultra Panavision. Also originally projected using the single-projector Cinerama system.
 * The Hallelujah Trail (1965) – filmed in Ultra Panavision. Also originally projected using the single-projector Cinerama system.
 * Battle of the Bulge (1965) – filmed in Ultra Panavision. Also originally projected using the single-projector Cinerama system.
 * Khartoum (1966) – filmed in Ultra Panavision. Also originally projected using the single-projector Cinerama system.
 * The Hateful Eight (2015) – Directed by Quentin Tarantino, first film shot in this process since Khartoum. Filmed in Ultra Panavision 70 and projected with the single-projector Cinerama system in selected theaters.
 * Christopher Robin (2018) – some scenes filmed in Ultra Panavision 70. Also filmed with Panavision 35 mm anamorphic lenses (on both 35 mm film and Arri Alexa digital cameras) and in Panavision System 65 with spherical lenses. The entire film is shown in the 2.40:1 aspect ratio.

Additionally, several films have been recorded digitally in conjunction with Ultra Panavision 70 lenses: Rogue One (2016), Bright (2017), Avengers: Infinity War (2018), Avengers: Endgame (2019) and The King (2019) with the Arri Alexa 65 camera, and The Hate U Give (2018) and Like a Boss (2020) with the Panavision Millennium DXL camera.
