Played By: Robert Mitchum
Movie: The Night of the Hunter (1955)

Imprisoned serial killer Harry Powell (Robert Mitchum) lucks up when he learns that his cellmate, who's about to hang for bad robbery, hid a ton of cash before he entered the clink. Since he's, you know, ruthlessly evil, Powell, fresh out of jail and cruising with his "LOVE" and "HATE" tattoos inked across the knuckles of both hands, seduces the executed man's widow, Willa (Shelley Winters), and plays daddy to his two children.

Demonstrating why he's more partial to the "HATE" tat, Powell eventually slices Willa's throat open. It's easy to see why Willa could've been so easily fooled in the first place—Mitchum portrays Powell with an icy charm that's hard not to like. He's the most dangerous kind of murderer: The guy who'll make you want to have a beer with him before he ends you. —MB
