Daniel Day-Lewis
There Will Be Blood (2007)
There's often a Freudian backstory that explains a villain's behavior, but not with Daniel Plainview, who seems to be a black force emerging from the bowels of the earth like the oil he covets. In his Oscar-winning performance, Day-Lewis makes Plainview's bloody deeds believable while preserving the mystery of his motives. Oh, and he's also got that nifty catchphrase. Gary Susman
