In 3/4 frontal view, the 'round' command pod of 2001's Discovery was distinctly 'ovoid' as it moved to the outer edges of the frame...the heads of the Russian scientists grouped around Heywood Floyd were frequently 'encephaloid'...and the space station itself distorted like crazy when the camera moved through its spokes. What didn't suffer were all of Kubrick's head-on 'tunnel' shots, including Trumbull's slit-scan 'walls of colour' during the climax...their stretching at the edges merely enhancing the barrel effect in those frames.Douglas R said:Although the 70mm Cinerama films didn't have the same apparent illusion of depth, they made up for that by not having the distracting lines separting the three images. Overall I thought it was a big improvement over three panel Cinerama and I don't remember noticing any severe distortion at the sides as you describe.
As for IAMMMMW, this stretching at the edges was unfortunately ever present in the group shots of the cast, less so with the panoramic chase scenes, except where they moved closer to the cars...which, even for the 60s looked very wide track.
