With a variation on the North By Northwest plot as innocent bumbler Gene Wilder is trapped on a cross-country train with villains out to kill him, and he himself has to evade the cops who think hes responsible for all the crimes.
The first film to partner Wilder with Richard Pryor, this is also the movie in which both performers careers started to nose-dive in terms of the quality of material they were willing to squander their comic talents on. Patrick McGoohan is aloof as the chief baddie, Arthur Hiller directs Colin Higgins hokey screenplay by numbers.
