The Child Catcher out of Chitty Chitty Bang Bang !!

The Firefly family from "House of 1000 Corpses" & "The Devil's Rejects".

Fifth Element - Jean-Baptiste Emanuel Zorg

Glenn Close as Alex Forrest in Fatal Attraction.

Darth Vader surely? Or maybe The Emperor? Honourable mentions to Blofeld, Norman Bates, Agent Smith (in the first Matrix at least), Max Cady (Mitchum's version) and Saruman (I don't know if you can count Sauron really).

Kathy Bates in Misery came to my mind first.

I am an animal!

The character, Cometus, in the movie "Gladiator". There was something very perverse about his wickedness. I disagree with this review which considers him as a sympathetic villain. I found him to be very hard to stomach throughout the entire film. http://www.ruthlessreviews.com/reviews.cfm/id/168/page/gladiator.html

I'm going with Dr.Evil :)

Hey bud, hows it going? I would say, The Joker, form Batman. I believe it was Jack Nickelson that played him.

Keyser Söze in the 1995 film The Usual Suspects,

Bruce Dern in the movie "The Cowboys."

I'm caught between Henry Fonda in Once apon a time in the West and The guy in 8 mm he was a sick, sick puppy.

Yul Brynner

Gary Oldman in "Bram Stoker's Dracula".

Chris took my answer. Except for one difference, before Jack and Jack was good too! I was thinking of the original Joker played by Ceasar Romero.

ABers, it's Jack Palance. He famously played a comic role in the Billy Crystal "City Slickers" film, but his REAL stuff was all scary! This is from imdb.com: (Go read the rest of the stuff about him.) "Few people know that veteran movie actor Jack Palance was a professional heavyweight boxer in the early 1940s. Fighting under the name Jack Brazzo, Palance a product of Lattimer Mines, Pennsylvania, won his first 15 fights, 12 by knockout before losing a 4th round decision to future heavyweight contender Joe Baksi on Dec. 17, 1940. With the outbreak of World War II, Jack Palance's boxing career ended and his military career began. Wounded in combat, he received the purple heart, good conduct medal, and the World War II Victory Medal. After the war he began his long and famous motion picture career. IMDb Mini Biography By: angelsunchained Mini Biography "He exemplified evil incarnate on film -- portraying some of the most intense and gripping villains witnessed in 50s westerns and melodrama -- and Jack Palance went on to win Oscar "Best Supporting Actor" nominations for two of them. It would take a grizzled, eccentric comic performance 40 years later, however, in order to grab the coveted statuette. "Of Ukranian descent, Palance was born Volodymir Ivanovich Palahniuk on February 18, 1919, in Pennsylvania coal country. His father, a miner, died of black lung disease. The sensitive, artistic lad worked in the mines in his early years but averted the same fate as his father. Athletics was his ticket out of the mines when he won a football scholarship to the University of North Carolina. He subsequently dropped out to try his hand at professional boxing. Although he certainly had talent and a good boxing record, he decided on a less abusive way of life. After decorated WWII service with the Army Air Force as a bomber pilot, he resumed college studies as a journalist at Stanford University and became a sportswriter for the San Francisco Chronicle. He also worked for a radio station until the acting bug bit."

And, Keithold, you are one of the few people who knows how to spell "villain." Congratulations.

I agree with Nuttsky ... Jack Palance was the best bad guy ... ... the vast majority of his roles were as the bad guy ...

Darth Vader.

Emperor Ming the Merciless. Not in the Flash Gordon TV show but in the Republic movie serials with Charles Middleton in the role. See http://www.youtube.com/watch?v=dpX_BJHEvZA for a sample.
