21 years after the release of his bristling satire Hollywood Shuffle, Robert Townsend was at Sundance to unveil his latest documentary Why We Laugh: Black Comedians on Black Comedy. Originally inspired by luminaries such as Richard Pryor and Redd Foxx, the film also casts a gentle eye towards Stepin Fetchit and other controversial figures in black comedy history.

Besides covering the impact of black comedians on mainstream popular culture, the doc also begs the question of what constitutes "the wrong kind of laugh." Here's hoping that Townsend's pic gets picked up by a distributor.
