During his prime, if Richard Pryor wasnt pissing as many people off as he was making them laugh hysterically at his jokes or pushing people's buttons, he likely felt he wasnt doing his job or making the intended impact. The 1970's and early 80's were his absolute prime in terms of comedy specials as well as roles in comedy/drama films like Busting Out, Brewster's Millions, Superman III, plus him co-writing the screenplay for Blazing Saddles.
