This article attempts a definition at what constitutes "character acting" in mainstream cinema in the United States and argues that throughout the peak of his film career-roughly, 1957 through 1976--Martin Balsam refined the definition of male character acting in American film, a parameter previously established by such skilled practitioners as Eugene Pallette and Claude Rains. Balsam did this through his ability to portray what can be termed "a man in a hat" portrayals: tartly humorous, reliable, and sometimes authoritative supporting characters, usually wearing a chapeau. This is clearly seen in such performances as the private investigator in Alfred Hitchcock 's Psycho (1960) and most interestingly, a partner in an unusual subway hijacking in Joseph Sargent's The Taking of Pelham One, Two, Three (1974).
