Peter Whitney, the shady bartender from THE BIG HEAT, was also an eclectic Dana Andrews actor, playing a clumsy banker in CANYON PASSAGE and then a formidable guard in THE IRON CURTAIN, motioning for Dana to turn around... how demeaning!
THE IRON CURTAIN, about a Russian code-breaker defecting in Canada, and one of the first Cold War movies ever made, was directed by William A. Wellman, who gave Dana Andrews his first important role in THE OXBOW INCIDENT almost a decade earlier.
