Creator Recovery: In 1979, Pryor went on a trip to Africa, and was so moved by the solidarity of the people there that he renounced his legendary N-Word Privileges. As he explained in his 1982 comedy special Live at the Sunset Strip:
Brooks also wanted him to play "Josephus" in History of the World Part I but Pryor was injured from the freebasing incident before production. He was replaced by Gregory Hines.
That freebasing incident also prevented him from appearing on The Muppet Show, forcing the staff writer, Chris Langham, to appear guest star instead.
Trading Places was originally written as another vehicle with himself and Gene Wilder, but when Pryor dropped out and Eddie Murphy signed on, Murphy asked that Gene Wilder be replaced, because he didn't want people thinking he was trying to be another Pryor.
