Samuel Michael "Sam" Fuller was an American film director, screenwriter, novelist, journalist, actor, and World War II veteran known for directing low-budget genre movies with controversial themes, often made outside the conventional studio system. Fuller wrote his first screenplay for Hats Off in 1936, and made his directorial debut with the Western I Shot Jesse James (1949). He would continue to direct several other Westerns and war thrillers throughout the 1950s.
