I think the point of the thread was to show actors that played villains exclusively or were almost always cast as the villain. DeNiro or Walken (while great as villains) probably do not fall into that group.
Timothy Carey -.
Alan Rickman is a great villain, Hans Gruber, Sheriff of Nottingham, Snape, etc.
Rutger Hauer (awesome in "The Hitcher" and "Blade Runner")
You guys disappoint me.
Did we leave your boyfriend out?
