Kirk Douglas, one of Hollywood's most celebrated icons, had an expansive film career that saw him acting into his late 80s before retiring in 2004, which included three Oscar nominations and an honorary Lifetime Achievement Oscar. His career apex came during a remarkable run in the 1950s and 1960s, when he emerged as arguably the biggest leading man in film. With his cleft chin and virile appearance, he played a series of tough, uncompromising men, scoring a parade of critical and commercial hits with Ace in the Hole (1951), The Bad and the Beautiful (1952), Paths of Glory (1957) and his best-known film, Spartacus (1960). Douglas died at age 103 on Feb. 5, 2020, and ET is taking a look back at some of Douglas' greatest films and onscreen performances.
