American film and television actor.

The son of a professional violinist, MacMurray learned a number of musical instruments, including violin, baritone horn, and saxophone, and in 1926 began a career as saxophonist-singer-comedian in dance bands and vaudeville, chiefly in Chicago, Los Angeles, and New York. He made his Broadway acting debut in 1930 in Three's a Crowd and his film-acting debut in 1935 in Grand Old Girl (though he had earlier worked as a movie extra). His third film, The Gilded Lily (1935), playing opposite Claudette Colbert, made him a star; thereafter he was a leading or character actor in dozens of films and made perhaps his best mark as a comedian in farce and breezy comedy, such as The Lady Is Willing with Marlene Dietrich (1942), Take a Letter, Darling with Rosalind Russell, No Time for Love with Colbert (1943), and The Egg and I with Colbert (1947). He was also effective in psychological drama, such as in Double Indemnity (1943), in which he fell victim to the wiles of Barbara Stanwyck, The Caine Mutiny (1954), in which he played a supercilious but weak-willed officer, and The Apartment (1960), in which he played a hypocritical businessman and womanizer. In the 1950s and '60s he appeared in few westerns and, most notably, in a variety of comedies in which he played a lovable bumbler, such as in the films The Shaggy Dog (1959), The Absent-Minded Professor (1961), and Son of Flubber (1963) and in the long-running television series My Three Sons (1960–72).
