It's always exciting when you don't know what will happen next in a Movie. Someone in a popular online forum asked other film fans for the best movies that keep you guessing. Here are 15 thriller movies to check out.

1. Wild Things (1998)

Wild Things may have the most twists per minute of any movie. The film starts as a story about a high school girl accusing a guidance counselor of assault. But it soon develops into a broader, more complicated story involving shifting alliances, romance, and murder.

2. The Skeleton Key (2005)

One film fan recommended the Southern gothic mystery The Skeleton Key, which follows a hospice worker who discovers a history of hoodoo in the home of one of her clients that may be impacting their lives now. It’s an atmospheric film that threads the needle between thriller and horror and features a fantastic cast, including Kate Hudson, John Hurt, and Gena Rowlands. 

3. Audition (1999)

Audition is Japanese auteur Takashi Miike’s most well-known movie for a reason. The film, which follows a man whose friend sets up auditions for women under false pretenses so that they can find him a new girlfriend, takes several twists and turns that lead to one of the most iconic finales in film history. 

4. The Handmaiden (2016)

Park Chan-wook is best known for his revenge thriller Oldboy. But when it comes to movies that keep you guessing and regularly shift your fundamental understanding of what’s happening, there may be nothing better than his film The Handmaiden. The movie plays out across three parts, each altering the audience’s perspective on the events that follow a young pickpocket being recruited by a conman to help con a wealthy heiress. 

5. Prisoners (2013)

Denis Villeneuve’s Prisoners isn’t an easy film to watch, but it is one of the best mystery thrillers of the last decade. The film follows parallel storylines of desperate parents and a young police detective, each investigating the abduction of children in different ways.

The parents kidnap a young man they suspect knows where their children are while the detective does good old-fashioned detective work. The answers they eventually uncover are horrifying, but the journey there is incredibly satisfying. 

6. Chinatown (1974)

One of the earliest neo-noir films, Chinatown is also one of the best. The film follows private investigator Jake Gittes (Jack Nicholson) as he is drawn into a multifaceted mystery that literally goes all the way to city hall. It’s a fantastic movie with a mystery that continues evolving and changing over the course of the film. 

7. Split (2016)

M. Night Shyamalan is famous for his twists, but none of his movies keep you unsure of what will happen next quite like Split. That’s likely due to the many personalities displayed by James McAvoy’s central character, who has 23 distinct personalities, and the increasingly creative and desperate methods that the three young women he’s kidnapped attempt.

There’s a now decently well-known final twist, but even if you know that, you still can’t guess how the movie plays out from scene to scene. 

8. Elle (2016)

Based on the novel Oh… by Philippe Dijan, Elle is one of the most beguiling and complicated movies of the last ten years. The film opens with a scene of violence, but instead of becoming a hard-edged genre film, or a grounded drama about the aftermath of that violence, it turns into a comedy.

Elle (Isabelle Huppert) doesn’t respond to her assault as she is expected to by those around her and seems more frustrated and upset by her family and work life than the violence she experienced. The film also plays out like a mystery as Elle works alone to unmask her assailant, and no one can guess how that mystery unfolds.  

9. Your Vice Is a Locked Room and Only I Have the Key (1972)

A very loose adaptation of Edgar Allen Poe’s The Black Cat, Your Vice is a Locked Room and Only I Have the Key tells the story of a wealthy but unsuccessful writer who becomes the key suspect when his mistress is found murdered. Things only become more complicated when his niece arrives and causes chaos by seducing his wife — and that’s just the first third of the movie. 

10. Under the Silver Lake (2019)

One of the most delightfully confounding mystery movies of the last few years, Under the Silver Lake follows unemployed Sam (Andrew Garfield) as he investigates the disappearance of a beautiful neighbor. But questions only beget more questions until a truly unexpected but somehow perfect ending that still doesn’t answer all the questions posed throughout the movie.

11. Good Time (2017)

This is a movie that keeps you guessing less because there are multiple twists and more because our protagonist is an unhinged and desperate man. The film follows petty criminal Connie (Robert Pattinson) throughout one night as he tries to think of ways to get his brother out of police custody while at the same time keeping himself out of custody for the failed bank robbery they committed together.

It’s a thrilling movie that is essentially the cinematic equivalent of a panic attack: equal praise and warning. 

12. Mother! (2017)

Another film that can’t be said to have “twists” so much as the entire movie is a thrilling question mark. The film centers on a couple whose idyllic home is visited by more and more people over a few days. It’s unclear what these visitors want, or who exactly they are, but their arrival presages a huge change, but what kind? Mother! is far from a standard thriller or standard anything, but it’s one of the most exciting movies of recent years.  

13. Parasite (2017)

Parasite is a thriller that looks at the issues of class differences when a parasitic relationship is formed between a lower-class family and their upper-class employers. As they all get closer, the lies and secrets hidden by both families are revealed.

14. Mulholland Drive (2017)

Mulholland Drive takes viewers on a wild ride when a woman gets in a car wreck and can't remember what happened before the accident. With the help of an upcoming actress, the two go on a wild journey to figure out the truth. 

15. The Village (2017)

This M. Night Shyamalan movie, of course, comes with a trademark plot twist that's so typical of Shyamalan movies. In a 19th-century village, a group of people live in fear of leaving the town. But when a blind woman leaves the town, the truth about the village is explored.
