I’d be very interested to know the aspect ratios of all these versions.
You may already be aware, but the 35mm releases were 2.39:1 (actually 2.394285714285714:1). That is a result of the SMPTE standard for projection apertures from October 1971 to August 1993. For the 70mm (which was blown up from the 35mm original) it was 2.2:1 (2.197701149425287:1), losing a small slice of the left and right from the 35mm image. What was actually projected in individual theaters likely varied from these standards.
The original video releases for all formats (VHS, BetaMax, CED VideoDisc, & LaserDisc) were all 4:3 pan & scan. After that it gets more complicated.
