Someone had the great idea to make the sidekick a Black Dude in a Buddy Movie and they struck gold, forever changing how movies are cast. It also launched stand up comic Richard Pryor into orbit. The Movie stars Gene Wilder and Jill Clayburgh (They have chemistry together) in an old fashion train journey picture reminiscent of Alfred Hitchcock. All the cast is marvelous especially the great Patrick McGoohan as a colorful villain. There would be no Eddie Murphy, Chris Rock, Chris Tucker or Martin Lawrence if there hadn’t been a Richard Pryor breakthrough.
