Lee MarvinWiki info
In 1950, Marvin moved to Hollywood. He found work in supporting roles, and from the beginning was cast in various war films. As a decorated combat veteran, Marvin was a natural in war dramas, where he frequently assisted the director and other actors in realistically portraying infantry movement, arranging costumes, and the use of firearms. His debut was in You're in the Navy Now (1951), and in 1952 he appeared in several films, including Don Siegel's Duel at Silver Creek, Hangman's Knot, and the war drama Eight Iron Men. He played Gloria Grahame's vicious boyfriend in Fritz Lang's The Big Heat (1953). Marvin had a small but memorable role in The Wild One (1953) opposite Marlon Brando (Marvin's gang in the film was called "The Beetles"), followed by Seminole (1953) and Gun Fury (1953). He also had a notable small role as smart-aleck sailor Meatball in The Caine Mutiny. He had a substantially more important part as Hector, the small-town hood in Bad Day at Black Rock (1955) with Spencer Tracy. Also in 1955, he played the interesting role of a somewhat lovelorn and touching (though thoroughly no-good) bank-robber in Violent Saturday.
