Gene Wilder and Richard Pryor were the greatest comedic duo of all time. In this clip, Gene is deaf, and Richard is blind. One of the all-time-great comedies. See it if you haven't.

QUESTION: Name the four movies that they starred in together.

And, for the bonus points, name the other movie they were going to star in together. It fell through because of Pryor's drug and alcohol abuse on set.
