No. 6.Alan Rickman in Die Hard. This guy is born to play a Villain and this is his finest hour.
No 5. Hal 9000 From 2000 a Space Odyssey . Chilling computer logical voice. Scary biscuits
No 4. The Wet Bandits, They got that pesky Kevin McAllister twice in Home Alone.
No 3 Dr. Hannibal Leckter. Enough Said.
No. 2 Darth Vader. Would be too predictable not to be number one.
No. 1 . Nazi s. Where would all those films be without random Nazi's to shoot.
