Lee Marvin was an American film and television actor. Known for his bass voice and premature white hair, he is best remembered for playing hardboiled "tough guy" characters. Although initially typecast as the "heavy", he later gained prominence for portraying anti-heroes, such as Detective Lieutenant Frank Ballinger on the television series M Squad (1957–1960). Marvin's notable roles in film included Charlie Strom in The Killers (1964), Rico Fardan in The Professionals (1966), Major John Reisman in The Dirty Dozen (1967), Ben Rumson in Paint Your Wagon (1969), Walker in Point Blank (1967), and the Sergeant in The Big Red One (1980).
