U.S. motion-picture director popular in the 1930s and '40s for his tough, masculine films.

Walsh began acting for the stage in 1910 and on film in 1912, the same year that he began directing. He played John Wilkes Booth in D.W. Griffith's greatest success, The Birth of a Nation (1915), and went on to direct about 200 motion pictures, usually characterized by their simplicity and quick action.

In 1949 he completed the film White Heat, a classic study of a pathological criminal. Other of Walsh's more complex pictures include High Sierra (1941), a sympathetic portrayal of an aging criminal whose life ends in tragedy, and The Naked and the Dead (1958), an effective translation of Norman Mailer's novel into film. Walsh's other films include: The Thief of Bagdad (1924), What Price Glory? (1926), The Roaring Twenties (1939), They Died with Their Boots On (1941), The Tall Men (1955), and A Distant Trumpet (1964).
