White Heat

"Made it, Ma! Top of the world!" —Cody Jarrett

White Heat is a 1949 Warner Bros Film Noir directed by Raoul Walsh and starring James Cagney. Cagney is Cody Jarrett, the violent and emotionally unstable gang leader who still has a soft spot for his Ma. After pulling off a train heist, he gets arrested and convicted for a robbery he didn't commit (as part of an alibi he'd previously arranged). Waiting in prison until the heat is off, he's worried about Big Ed, his second-in-command, taking control of his gang and his (unfaithful) wife. When he hears Ed has killed his mom, an enraged Cody busts out, determined to rub out Ed and regain control of the gang. What he doesn't know, though, is that a trusted fellow con who escaped with him is really an undercover cop. It all comes to a spectacular finish during another heist, where Cody makes it to the top of the world...
