One of Ashton Kutcher's best movies, The Butterfly Effect is about a college student named Evan who starts to black out with intense headaches. These experiences trigger time travel while he's unconscious, making him relive dark childhood memories. As he begins to alter his own past as well as that of his friends, Evan soon realises there are terrible consequences to these changes in the present day. These eerie, twisted alternate realities mirror Donnie Darko's own bleak parallel universe.
