From the intimidatingly intelligent to the criminally insane, audiences have been treated to just about every type of movie villain imaginable over the years. While many fall into the same tired archetypes though, there are some who have been able to transcend tropes and remain memorable long after their on-screen debuts.

A weak villain can not only detract from a great movie but also prevent other characters from reaching their full potential. In many ways, they serve as foils for the movie's main protagonists whilst also being responsible for injecting tension into proceedings through the creation of conflict and chaos. It's those who achieve these things most effectively whose actions are indelibly etched into the minds of those watching.

10 The Joker (Heath Ledger) - Batman

Many actors have been given the opportunity to play Batman's nemesis on the silver screen, but none have been able to capture the character's chaotic nature quite as well as Heath Ledger. Unlike Jokers prior and since, he offers no hint of remorse or reason, which in turn, propagates the idea that he is capable of just about anything. This keeps the audience guessing while allowing tension to mount to near palpable levels.

He's a competent fighter, but it's the psychological threat that he poses which makes him so dangerous. One of the few things that separate Batman from the criminals that he fights is his strict moral code, and this is something that the Joker exploits on multiple occasions. Armed with the knowledge that Batman can't kill him and blessed with the ability to inspire and insight chaos and carnage, Batman can never truly defeat the Joker without first losing himself.

9 Agent Smith (Hugo Weaving) - The Matrix

That Agent Smith is so good at his job is not too surprising considering that it's exactly what he was programmed to do. That he despises it and the artificial world in which he carries it out, however, makes him a far more interesting character and maybe even a little relatable, too. This not only sets him apart from the other agents but also most other movie villains.

From the first moment the audience is introduced to Smith, he's shown to be completely remorseless, and his ability to manipulate the matrix gives him an air of unstoppability that very few antagonists possess. Even after he's defeated at the end of the first movie, he's able to find a way to come back stronger than ever, requiring Neo to use every bit of his physical and mental strength to persevere.

8 Voldemort (Ralph Fiennes) - Harry Potter

One of the things that makes Voldemort so intimidating is the groundwork that was laid in establishing his character prior to his first appearance. So much of the first few books and movies is spent discussing the Dark Lord's past indiscretions, that by the time he returns to physical form, he needs no introduction whatsoever. That one of his first acts is to torture and then try to kill Harry only serves as confirmation of what the audience already knows.

Voldemort's complete inability to feel love, and his rampant pursuit of power, sees him commit some unspeakable acts, but he's also an incredibly effective leader. He's able to inspire others to do his bidding so effortlessly, allowing him to seize control of the Wizarding World almost immediately after his return. Had he had a better understanding of wand lore, his reign of terror may never have come to an end.

7 Hannibal Lecter (Anthony Hopkins) - Hannibal

For the longest time, Anthony Perkins' portrayal of Norman Bates in Psycho was the gold standard when it came to on-screen serial killers - and for very good reason. That all changed, however, when the world was reintroduced to Hannibal Lecter in the 1991 psychological horror movie Silence of the Lambs.

Although the character had first appeared some five years earlier in Manhunter, it wasn't until Anthony Hopkins stepped into the role that he truly became terrifying. With his incredible intellect and unmatched understanding of the human mind, Hopkins' Hannibal is marvelously menacing and his cannibalistic tendencies only make him a more fearsome antagonist. Even incarcerated, he's able to send shivers down the spine, and his ability to do so increases exponentially following his escape towards the end of the movie.

6 Scar (Chiwetel Ejiofor) - The Lion King

There have been some wonderful Disney villains over the years, but the likes of Jafar and Cruella are simply no match for Scar. While many of his peers begin their respective movies in positions of power and influence, this second son is instead forced to fight his way to the top by any means necessary. He's ultimately smart enough to realize that he's no match for his brother head-on, so he uses brains rather than brawn to get the job done.

As upsetting as the death of Mufasa may be, it's difficult not to be impressed by Scar's ingenuity. Every piece of the puzzle is laid perfectly in place and he's able to take control of the pride with very little resistance as a result. Had he only had the foresight to finish Simba off at the same time, Pride Rock might still be suffering through his lackluster leadership to this very day.

5 Hans Gruber (Alan Rickman) - Die Hard

Many villains draw their power over the audience through their wanton acts of violence, and while this is certainly an effective method, Hans Gruber shows that there is another way. He's sophisticated, highly intelligent, and almost entirely motivated by money. In many ways, he is the polar opposite of the Joker.

McClane may mock Gruber for being little more than a bank robber, but ultimately it's this that makes him such an effective villain. He knows exactly what he wants and although he's willing to kill to get it, he only uses lethal force when he deems there to be no other way. The back and forth between him and Willis' character often plays like a game of mental chess and this makes both characters far more compelling as a result.

4 The T-800 (Arnold Schwarzenegger) - Terminator

Although Arnie's character serves as one of the heroes in some of the later Terminator movies, he hasn't always been one of the good guys. In his debut appearance, the T-800 was one of the most terrifying villains to ever grace the silver screen; not just because of his capacity to cause carnage, but also due to his seemingly impenetrable robotic endoskeleton.

Much like the terminators that show up in subsequent movies, the T-800 is able to handle pretty much anything that the heroes throw at him. He keeps on coming no matter what, and this creates an air of inevitability, leading viewers to see it as a case of 'when', not 'if' he will achieve his primary directive.

3 HAL 9000 (Douglas Rain) - 2001: A Space Odyssey

While an artificial intelligence system sending unstoppable cyborgs into the past certainly makes for a captivating concept, the idea of technology turning against its creators was far from new. One of the earlier and more prominent examples of this came in the form of the HAL 9000 from Stanley Kubrick's 1968 sci-fi classic 2001: A Space Odyssey.

Its soft, calm voice may at first seem reassuring, but as conflicts in the AI's programming begin to lead to more and more erratic behavior, the emotionless responses become increasingly disconcerting. It's perhaps this and the lack of any real physical form besides a blinking red dot and a camera lens that makes the HAL 9000 such a fantastic antagonist; not to mention an incredibly memorable one.

2 Freddy Krueger (Robert Englund) - Nightmare On Elm Street

Murder is one of the most powerful weapons that a villain has at their disposal, but there seems to be something of an unwritten rule when it comes to killing children. Unfortunately for the kids of Elm Street, nobody seems to have told claw-handed killer, Freddy Krueger, about this unspoken age limit.

The ages of his victims, and the unique nightmare mechanism by which he kills them, really sets Freddy apart from the likes of Jason and Leatherface, while the huge variety of techniques that he uses to take his victim's lives keeps things feeling fresh, despite his many appearances over the years. His unquenchable blood lust and pulsating punchlines are truly terrifying and makes the Nightmare on Elm Street killer a difficult one to forget.

1 Darth Vader (James Earl Jones / Dave Prowse) - Star Wars

He may only be the second in command, but his complicated backstory and prominence throughout the original trilogy make Darth Vader a much more compelling villain than the emperor could ever be. He's ruthless, incredibly powerful, and his familial ties with Luke makes their duels all the more meaningful and extremely engrossing.

He displays no signs of compassion throughout the majority of the first three movies and has no reservations about striking down his former mentor or slicing off his son's hand. He obliterates the people of Alderaan without giving it a second thought and repeatedly murders his own men as a result of his uncontrollable rage. Although he ultimately has a change of heart, Vader's menacing presence is ultimately what made the movie's so successful and he himself one of the most memorable movie villains of all time.
