Donnie Darko (2001)

In 1988, teenager Donnie Darko has been seeing a psychiatrist because of his troubled history. On October 2, Frank , a menacing, demonic-looking rabbit with an eerie, hypnotic voice, draws Donnie out of his room to tell him that in 28 days, 6 hours, 42 minutes, and 12 seconds, the world will end. While Donnie is outside, an airplane jet engine crashes through his bedroom. The next morning, Dr. Fisher and Jim Cunningham , a motivational speaker find Donnie sleeping on a golf course. Donnie returns home to find police and firemen there. No one knows where the engine has come from and no airplanes were reported as flying in the vicinity.

The following day, Donnie meets Gretchen Ross , a new student who becomes Donnie's love interest. His father, Eddie , takes Donnie to his therapist, Dr. Lillian Thurman , and nearly runs over Roberta Sparrow , a seemingly senile old woman known as "Grandma Death." Dr. Thurman increases Donnie's medication and begins hypnotherapy. Frank continues to appear, and manipulates Donnie to commit a series of crimes. Frank also tells Donnie about time travel while he is watching a film at the theater with Gretchen Ross. Donnie floods the school, steals his father's gun, and burns the home of Cunningham, where firemen uncover a "kiddie porn dungeon".

Donnie and older sister Elizabeth throw a Halloween party while their father is away in New York and their mother, Rose , and younger sister Sam , are away at a dance competition. Gretchen comes to Donnie's house in tears for safety because her mother has suddenly disappeared, likely because of her threatening stepfather, and it is implied she and Donnie have sex for the first time at the party. At midnight, Donnie realizes 28 days have passed and only 6 hours remain until the end of the world. Donnie visits "Grandma Death" along with Gretchen and two friends. They are assaulted by the high school bullies and Gretchen is knocked unconscious. A car swerves to avoid "Grandma Death", but runs over Gretchen, killing her. As the bullies run off, a man wearing a rabbit costume emerges from the car, realizing what has happened. It is Frank. Frank yells at Donnie, who shoots Frank in the eye with his father's stolen pistol. Donnie carries Gretchen's lifeless body home, places her in the family car, and speeds away. For once, Donnie, now smiling, seems at peace as a vortex engulfs the jet carrying his mother and sister. Just as the storm causes an engine to fall off, Donnie transports it back in time – 28 days earlier – using a wormhole.

In the revised timeline, Donnie chooses to stay in bed. He laughs and turns over as if to sleep just as the jet engine crashes through his bedroom, killing him. As his body is taken away the next morning, Gretchen passes by on her bike and is informed by a neighborhood boy about what has happened. Gretchen tells him that she did not know Donnie, and she gives a sympathetic wave to Rose.
