The second of two films shot in the MGM Camera 65 process (eight more would be shot after the process was re-named Ultra Panavision). It was intended to be the first, but production delays led to MGM using it first on L'albero della vita (1957). Like the Todd-AO format (introduced in 1953), MGM Camera 65 used 65mm negative stock that was then printed to 70mm film for roadshow release prints, or optically printed down to 35mm for general release. Unlike Todd-AO, though, Camera 65 operated at a standard speed of 24 fps from the beginning and utilized 1.25x anamorphic lenses to optically squeeze an aspect ratio of 2.76:1 into the 2.20:1 Todd-AO frame. These lenses were developed and manufactured by [error], a natural evolution on its work to improve the quality of anamorphic camera and projection lenses for the CinemaScope system. The extra 5mm of film between the 65mm negatives and 70mm prints was comprised of 2.5mm outside the perforations on either side of the film, allowing for up to four stripes of magnetic oxide carrying up to six discrete channels of sound--offering greatly superior sound quality in comparison to the mono optical tracks on 35mm prints at the time. When MGM sold its camera department to Panavision in 1961, the Camera 65 process was renamed Ultra Panavision 70 but remained technically identical. The complexity of anamorphic photography and post-production, however, meant the system was short-lived--especially due to the use of unique 1.25x anamorphic lenses rather than the 2x power used for CinemaScope--and the process was last used for Khartoum (1966). Most of the cameras were used on Super Panavision 70 productions--Panavision's exact copy of the non-anamorphic 24 fps Todd-AO process--before being replaced by the Panaflex 65 cameras used in Panavision System 65. Notably, due to the complexity and cost of projecting anamorphic 70mm prints, recent re-issue 70mm prints of "Ben-Hur" have been printed from optically unsqueezed negatives to allow their projection on normal 70mm equipment with only slight cropping of the sides of the picture.
