There's an interesting SF novel by Connie Willis, "Remake," in which Hollywood is no longer making any more live movies. Instead, they just fiddle with old films, changing them around and putting in animations of old movie stars.
The hero's job is to go through all the old movies and remove all the cigarettes and alcohol, so as to make them politically correct. Edit the cigarette out of the star's fingers, and so forth.
He has a hell of a time with "Casablanca," especially when his boss tells him it needs a happy ending.
Must get that book,sounds hilarious.
What are they gonna do when some leftist wants to make a movie about FDR and how the New Deal saved America? Have him in a wheelchair with a lollypop in his mouth?
I thought the ending of Casablanca WAS a happy ending.
