During the late 1950s, the Hollywood filmmaking community decided that changing from filming in the commonly accepted 35 mm format to 65 mm film would provide viewing audiences with an enhanced visual experience, compared to an anamorphic widescreen image.
Some of the films made in Super Panavision 70 were presented in 70 mm Cinerama in select theaters.
Special optics were used to project the 70 mm prints onto a deeply curved screen to mimic the effect of the original three-strip Cinerama process.
The System 65 lenses were all a medium-format variant of lens designs from the (then) current line of Panavision Primos.
In the 2010s, this renaissance finally materialized following a string of successful films from director Christopher Nolan, which were produced and screened in 70 mm IMAX.
