Jack Nicholson in The Cry Baby Killer (1958)
One of the better-known and most-respected screen actors of our time, Jack Nicholson has won three Oscars and has been nominated for many more. But before that he had to pay the rent. At age 21, Nicholson got a part in The Cry Baby Killer, a super low-budget, not-yet-ready-for-prime-time movie about an unstable young man who finds himself in dire circumstances. Nicholson plays Jimmy, the "cry baby killer," and does a good job with a weak script. But if you want to see Jack at his best, check out One Flew Over the Cuckoo's Nest, The Shining, or The Departed.
