Richard Pryor is a legendary comic. His ground-breaking take on America have been massively influential to later generations of comedians.
His film work has been much more hit and miss. He had some classics, but he also had some real clunkers. His best remembered movies are probably just his live stand-up acts.
The man had a crazy life, which made for some great laughs for us, even if it meant a great deal of pain for him.
