Perhaps one of the biggest bullies in movie history, we watch Biff terrorize the McFly family over three movies with his butthead taunts. And with that, actor Thomas F. Wilson will always be a part of movie history.Gary Oldman loves every moment while playing this crooked cop who needs EVERYONE!! to take out a hitman (Jean Reno) who just wants to be left alone.The evil overlord of the Sith is the ultimate puppet master of a galaxy far, far away.This terrorist mastermind may not have been as memorable if it weren't for the amazing acting by Alan Rickman, who made the character so fun to watch.Silence of the Lambs is so diabolical it gave us two memorable villains (we'll meet the other one later).Ted Levine's portrayal of the serial killer Buffalo Bill (real name James Gumb) who is in search of making the perfect woman suit from actual women's skin is horrific regardless how many times you've seen the movie.In Oliver Stone's gripping look at the Vietnam War the performance by Tom Berenger as the scarred-up, tough-as-nails Sgt. Barnes is a chilling one. He's so demented his men are convinced the only thing that can kill Barnes is Barnes.The off-camera life of actress Joan Crawford is brought to startling life thanks to Faye Dunaway's performance. An adaptation of the memoir by Crawford's adopted daughter Christina Crawford, we watch how the actress manipulated and abused her family.

Hedy Carlson's complete obsession with Allison (Bridget Fonda), even getting the same identical haircut she has, makes her a worthy addition to this list.There are some villains that are so bad you can't help but root for them and that's the case with the lead in one of Stanley Kubrick's most demented movies. Malcolm McDowell's sinister Alex and his ultra-violent ways lead to some very dark moments, but the way Alex does everything means you just can't turn away.Don't ever cheat on your partner. That's the moral of the story in Gone Girl, as Amy Dunne shows what payback is.

The T-1000, played by Robert Patrick, is also impressive because of the ground-breaking CGI that James Cameron used to pull off its liquid metal body.Leonardo DiCaprio's first time in a Quentin Tarantino movie is some pure evil s--- as he plays a super racist plantation owner. The performance is one of DiCaprio's most outlandish and shows that his talents are perfect for Tarantino's world.Like the T-1000, what makes Gollum so memorable is the CGI used to bring this evil character to life.

Aldo The Apache Raine (Brad Pitt) and his team of Basterds.This horrific villain with a love for his chainsaws from Tobe Hooper's classic still gives movie fans sleepless nights.Brad Pitt and Edward Norton combine their talents to present the duel personalities of the central figure in David Fincher's movie. There's the guy, who's fed up with life and goes off the grid (Norton) and then there's the guy, who builds a cult and tries to bring down capitalism (Pitt).Whether your favorite Pennywise is performed by Tim Curry or Bill Skarsgård, it doesn't matter.

Thanks to ol' Bruce there are people who are still scared to go in the water.Yes, Buffalo Bill is pretty bad in this movie, but it's Hannibal the cannibal who is the true villain.

It also led to the character being one of the most evil in the Coen brothers filmography thanks to his use of a coin to decide a person's fate and his weapon of choice, a captive bolt stunner.There have been many great portrayals of DC Comics villain The Joker, but Heath Ledger's went beyond any of them. Appearing in the middle movie of Christopher Nolan's Dark Knight trilogy, his performance would not just earn him an Oscar, but elevate the movie to become one of the best comic book blockbusters of all time.It's hard to think of a villain who is as memorable and has influenced so many others than Darth Vader. Whether he's Anakin Skywalker (Hayden Christensen) turning to the dark side (and killing younglings in the process) or as the Sith Lord, voiced by James Earl Jones, who can kill a man by crushing his throat by using the Force, Vader is the gold standard of villainy.
