Anton Chigurh
No Country For Old Men (2007)
Played by Javier Bardem

From his introduction — strangling a deputy on the floor — to his murder spree that ends the film, Anton Chigurh hovers over No Country like an impending storm. He's coming. And no one can stop him. Bardem lends the character a psychotic lack of remorse that's chilling. He hunts people, and never stops. Your only chance is fate itself, a coin flip.
