Ultra Panavision 70

From Wikipedia, the free encyclopedia

A frame from Ben-Hur, showing the extremely wide aspect ratio.

Ultra Panavision 70, also known as MGM Camera 65, was the marketing brand used to identify 65/70 mm movies photographed with Panavision anamorphic optics between 1957 and 1966.

The frame dimensions and six-track stereo soundtrack configuration of Ultra Panavision 70 were virtually identical to those established for the Todd-AO 65/70 mm process in 1955. However, the optics incorporated a 1.25X anamorphic "squeeze," yielding an ultra-wide projected aspect ratio of approximately 2.76:1.

[edit] History

The special optics were initially developed in association with Metro-Goldwyn-Mayer, who used it to photograph two movies, Raintree County (1956) and Ben-Hur (1959). These were advertised as being produced in MGM Camera 65.

MGM Camera 65 is a wide-screen film format developed by Metro-Goldwyn-Mayer in the 1950s, as a single-strip substitute for Cinerama. However, the screens used for showing Ben-Hur and Raintree County were not curved, as Cinerama and Todd-AO's were, but rectangular, in the manner of Cinemascope. The process used 65 mm film stock and a special anamorphic lens developed by Panavision, which imparted a slight horizontal squeeze by a factor of 1.25x. This yielded an aspect ratio of approximately 2.76:1, which was considerably wider than three-strip Cinerama. It was only used on fewer than a dozen films due to the extremely large and heavy cameras and its unusually wide aspect ratio, which was incompatible with most theaters. 35 mm anamorphic prints made from Camera 65 negatives were usually letterboxed at 2.55:1, and were indistinguishable from Cinemascope films. (However, when Ben-Hur was released on DVD, it was issued in its original 2.76:1 ratio, giving it possibly the "widest" letterboxing ever seen on a DVD. This accounts for the unusually large "black borders" that one notices when seeing the film in letterbox on a normal screen TV set.)

The process was subsequently refined, re-named Ultra Panavision 70 and used to photograph seven additional features.

Many of the films advertised in Ultra Panavision 70 were presented in 70 mm Cinerama in selected theaters. Special lenses were used to project a "rectified" (optically pre-distorted) 70 mm print onto a deeply-curved screen to mimic the effect of the original 3-strip Cinerama process.

Portions of the 1962 Cinerama feature How the West Was Won were photographed using Ultra Panavision 70, and then optically converted to the 3-strip format. ^[1]
