The great Richard Pryor, 65, has died at his home of cardiac arrest, his wife is telling reporters. The poor guy…multiple scherosis all those years and he only made one truly great film: Richard Pryor: Live in Concert, the 1979 doc about Pryor’s act (performed at the Long Beach auditorium, prior to his burning accident). Pryor’s performances in Silver Streak, Blue Collar and Stir Crazy were engaging, amusing, etc., but the ’79 concert film, directed by Jeff Margolis, was untempered genius.
