Silver Streak (1976)

Silver Streak, starring Gene Wilder, is the classic tale of being in the wrong place at the wrong time. This story takes you along the journey of a man mistaken for a killer as he tries to prove his innocence. 

This comedy decides to aid the hero by dressing him up in blackface, which is an immediate strike that is no longer tolerated. With Richard Pryor telling costar Gene Wilder in one scene “how to be black,” it’s pretty clear that a take on race relations like this wouldn’t work today.
