inspired by Jekelish in the Best Commercial's thread, I start this category off with Wes Studi's terrifying portrayal of Magua in Michael Mann's under-appreciated version of Last of the Mohicans
He was also great as Snape, although ultimately not a villan. Just a great actor.He was a great villain. And on the topic of native American 'villains', he's the bald guy in tons of movies (Dances with Wolves???) and almost always plays the bad guy. I can't remember his name for the life of me.
Another one of my favorites is Alan Rickman as Hans Gruber in Die Hard.
Johnny Lawrence in The Karate Kid (also in the movie about a girl who disguises herself as a boy, then flashes the goods at the end)
Robert Mitchum in Night of the Hunter
a great, great movie if you haven't seen it
Mitchum is an ex con passing himself off as a preacher . . . won't tell you the rest, but watch as he explains why he has "LOVE" and "HATE" prison tats across his knuckles:
