From All Movie Guide: American actor Elisha Cook Jr. was the son of an influential theatrical actor/writer/producer who died early in the 20th Century. The younger Cook was in vaudeville and stock by the time he was fourteen-years old. In 1928, Cook enjoyed critical praise for his performance in the play Her Unborn Child, a performance he would repeat for his film debut in the 1930 film version of the play. The first ten years of Cook's Hollywood career found the slight, baby-faced actor playing innumerable college intellectuals and hapless freshmen (he's given plenty of screen time in 1936's Pigskin Parade). In 1940, Cook was cast as a man wrongly convicted of murder in Stranger on the Third Floor (1940), and so was launched the second phase of Cook's career as Helpless Victim. The actor's ability to play beyond this stereotype was first tapped by director John Huston, who cast Cook as Wilmer, the hair-trigger homicidal "gunsel" of Sidney Greenstreet in The Maltese Falcon (1941).
