Just found out the #VHS release of Spider-Man is made using the open matte version of the movie and so actually shows more than the widescreen version. And I think that is: extremely cool.
(Despite my love of VHS, I actually don't know exactly how common this was as a practice. I know they did it with the 1990 TMNT, resulting in it being possible to see where the New York city skyline backdrop ends at the top in one shot.)
