Probably Robert Mitchum's best-known performance was in this extremely creepy suspense-horror film from 1955. It's the one where he has "Love" and "Hate" tattooed across his knuckles. He plays Harry Powell, a preacher and psychotic serial murderer who one day gets married to Willa Harper, newly widowed and mother of two. Willa's previous husband has just been hanged for robbing a bank and killing two men in the process, and Harry is hoping to get his hands on the hidden money. And then it gets really messed-up.
