Lee Woo-Jin, Oldboy
He exhibits nearly all the traits in the definition and he constructs such an elaborate and depraved revenge plot I think he definitely falls into the psychopath category.
Reverend Harry Powell, Night of the Hunter
Mitchum with the quiet menace.
Daniel Plainview, There Will Be Blood
Willing to use anything and anyone to get what he wants.
Frank Booth, Blue Velvet
Dennis Hopper plays himself.
Asami Yamazaki, Audition
