It’s not film, but the Apple II (1971) used a monochromatic display or something for technical reasons. I’m trying to find the quote but unfortunately I can’t so this is from memory. It was something like going with black and white allowed them a better frame rate/resolution over color (and for cheaper).
It’s possible similar tradeoffs existed for monochromatic film into the '90s.
Maybe I’m getting it confused with a different apple computer then besides the apple 2. I definitely have seen a clip talking about this. Maybe the original iMac or something.
