Who remembers when movie cinemas had a curtain over the screen?
Here's my memory of it.
You come into the cinema, lights are on, maybe some music is playing. Then they start projecting as the curtain pulls back, creating a weird image over a curtain.
You watch a bunch coming attractions and commercials and then they curtain closes again, and then reopens even wider for the feature length movie.
I'm not sure what year they got rid of this but I think it was early 90s.
