In some of Hollywood’s greatest movies, viewers will have questions that remain unanswered after the credits. These enigmas, some intentional, some not, have led to a host of fan theories and speculation about them. Below are ten iconic unsolved movie mysteries.
Inception (2010)

The ending of the film has Cobb spinning his top, and we wonder if he’s still dreaming or if he’s just come back to reality. Christopher Nolan is leaving the answer somewhat open to interpretation.
The Thing (1982)

Following the destruction of the Antarctic base, MacReady and Childs sit side by side, in the cold. The movie doesn’t actually make clear whether or not either of the survivors has been assimilated by the alien being.
Pulp Fiction (1994)

It’s hardly been solved yet: the glowing briefcase. Quentin Tarantino doesn’t give you any information about what’s inside so that you can draw your own conclusions.
Blade Runner (1982)

But is Rick Deckard really a replicant? There are subtle hints throughout the film hinting at both possibilities, and various cuts of the film have only perpetuated the debate.
No Country for Old Men (2007)

Llewelyn Moss’ murder is never seen, and it is unclear what happens to Anton Chigurh. The Coen Brothers aren’t in the business of giving easy answers, and they leave their viewers with questions.
Donnie Darko (2001)

Viewers have been left in awe of the film’s complicated timeline, alternate realities, and mysterious rabbit Frank. There are many different versions of the story, and there is no one version that will answer all the questions.
Mulholland Drive (2001)

The film is a psychological thriller with elements of dreams, identity, and reality, where it is hard to pinpoint an exact definition. It’s one of Hollywood’s most talked-about cinematic mysteries to this day.
2001: A Space Odyssey (1968)

Stanley Kubrick’s Sci-Fi masterpiece leaves so much open to the imagination that the appearance of the mysterious monolith and the meaning of the Star Child are some of its many questions left unanswered.
Shutter Island (2010)

The final conversation between Teddy and Dr. Sheehan raises one lasting question: Did Teddy truly relapse into his delusion, or did he knowingly choose his own fate?
Enemy (2013)

The shocking ending of the film, in which the giant spider is let off on the screen, has left many people debating the film for years. Director Denis Villeneuve doesn’t give any real explanation, and the symbolic meaning is left open to interpretation.
