Star Trek VI was the only Trek film to be shot on Super-35, with a negative aspect ratio of 1.66.
Apparently, according to Memory-Alpha, early full screen TV broadcasts and VHS releases were reduced to 1.33 using the original 1.66 print, opening up the top and bottom but cropping the sides.
Does anyone own any of these VHS releases and/or broadcasts? I’d love to see how it was originally framed and if a 1.78 release would ever be possible.
