10 Movies That Secretly Revealed Their Endings
9. 12 Monkeys - The Beginning Was The End
12 Monkeys is one of Terry Gilliam's more bizarre films... In 2035 the human race is living underground after a deadly virus has made the surface inhospitable. James Cole (Bruce Willis) is sent back in time in an attempt to stop the scientist who created the virus from doing so - it's sort of Terminator 2 meets Contagion.
Early on the audience is shown Cole as a young boy, witnessing a man being gunned down at an airport. From the outset of the film Cole is haunted by a reoccurring dream of this incident.
Cole travels back in time throughout the course of the movie, at one point being incarcerated in an insane asylum, along with a crazed environmentalist, Jeffrey Goines (Brad Pitt). Cole explains to Goines that he must save the human race from a deadly virus which will return the planet to the animals. This inadvertently encourages Goines to steal a virus from his father, who happens to be a virologist.
As the narrative plays out it becomes clear that Cole being sent back in time is the trigger that leads to the downfall of humanity. Towards the end of the movie Cole tries to stop one of Goines' associates from boarding a plane and releasing the virus around the globe.
His plan fails when he's gunned down, however. It's revealed that Cole's recurring nightmare was actually him witnessing his own death. The movie ends with pretty much the same scene it begins with, only from a different angle.
