Folks reasonably assume footage from behind-the-scenes featurettes are “truth”, but it is now standard practice for studios to alter footage from “making-of” videos.

(These gray screens are actually blue screens on the set of “Superman” (2025).)

"come on, todd - nobody sees stuff like this and jumps to wild conclusions about how movies are made and then makes extremely simplistic YouTube video essays spreading misinformation and then tens of thousands of people get bad information about how movies are made"

me:

@tvaziri I know what you’re saying in all this (and really appreciate the fight you are in) but that blue superman suit against a blue screen gives me the Willies. Much of blue/green screen ends up getting roto’d in the end either way. But why do you think they didn’t use green for this scene at least? I’m a comp artist, with not much on-set experience. Help me understand.
