It's a common trope that audiences root for the hero, the underdog who overcomes adversity and vanquishes evil. However, some films owe their success, and lasting impact, to the villains who captivate, terrify, and even, in some twisted way, inspire the audience. These villains aren't just obstacles; they are often the driving force behind the narrative, their actions and motivations shaping the entire story. Here are eight films where the villain's impact is undeniable.

1. The Dark Knight (2008): Heath Ledger's portrayal of the Joker is widely regarded as one of the greatest villainous performances in cinematic history. The film's success is largely attributed to the Joker's chaotic and unpredictable nature, his twisted philosophy, and his relentless pursuit of proving that everyone is susceptible to corruption. The Joker's actions directly challenge Batman's moral code, pushing him to his limits and forcing him to make impossible choices. The film becomes a thrilling examination of order versus chaos, with the Joker's victory marked by the moral compromises Batman is forced to make.

2. The Silence of the Lambs (1991): Anthony Hopkins' portrayal of Hannibal Lecter is chilling and captivating. Lecter, a brilliant but incarcerated cannibalistic serial killer, becomes integral to the plot as he provides insights into the mind of another killer, Buffalo Bill. Lecter's intelligence, manipulative nature, and unsettling charm make him a compelling character. The film's suspense and psychological depth are heightened by Lecter's presence, making him far more memorable than the protagonist, Clarice Starling.

3. Star Wars: Episode III – Revenge of the Sith (2005): This film depicts the complete transformation of Anakin Skywalker into Darth Vader and the fall of the Jedi Order. Palpatine's manipulation and the execution of Order 66, which leads to the Jedi's near-extinction, showcase the power of the dark side. The film's tragic elements and the establishment of the Empire make it a dark but compelling chapter in the Star Wars saga. Even though Obi-Wan wins the lightsaber battle against Anakin, the Empire ends up ruling the galaxy.

4. The Usual Suspects (1995): This crime thriller hinges on the mysterious figure of Keyser Söze, a criminal mastermind whose existence is shrouded in legend. The film's intricate plot and non-linear storytelling culminate in a shocking twist revealing Verbal Kint to be Söze himself. Söze's deception and successful evasion of justice solidify the film's reputation as a study in cunning and power.

5. Psycho (1960): Alfred Hitchcock's Psycho owes much of its enduring impact to Anthony Perkins' portrayal of Norman Bates. Bates is both eerily vulnerable and terrifyingly unhinged. The film masterfully blends suspense and psychological horror, with Bates's complex character remaining the most memorable aspect of the movie.

6. Gone Girl (2014): Rosamund Pike's portrayal of Amy Dunne transforms what could have been a simple mystery into a dark exploration of marriage and manipulation. Amy's elaborate scheme to frame her husband for her murder showcases her intelligence and ruthlessness. The film's success lies in its exploration of moral ambiguity and the unsettling reality that Amy "wins" by trapping her husband in their dysfunctional relationship.

7. No Country for Old Men (2007): Javier Bardem's Anton Chigurh is a chilling and relentless hitman. His unwavering commitment to his task, coupled with his strange code of ethics, makes him a terrifying force of nature. The film's bleak outlook and exploration of nihilism are embodied in Chigurh's actions, making him a central figure in the narrative's impact.

8. Hereditary (2018): This horror film takes a sinister turn as the Graham family is revealed to be pawns in a supernatural plot. The grandmother, Annie's mother, orchestrates events from beyond the grave as the leader of a coven that worships the demon king Paimon. The coven ultimately succeeds in possessing Peter with Paimon, marking a disturbing victory for the villains.
