Ask for a movie, the ending is that men go back to the past and women don't know themselves, but they pass by in the street but are strangers?

At the end of the film, it goes back to the beginning of the film: Evan runs into his doctor's office (the result of this historical change makes his diary disappear) and wants to change history for the last time through the pictures of home movies. Here, the director arranged four endings altogether.

1. This is the ending of the director's version: At the beginning of life: Evan's home movie is that Evan's mother is about to give birth to Evan. Evan, who entered history, decided to end it all by himself. He grabbed the umbilical cord with both hands and ended his upcoming life. In real life, there is no Evan. Kelly and Tommy are guarded by a divorced mother, far away from BT's father, so naturally there is no detonator incident. At this time, Evan's father has entered a mental hospital, so the child finally held by his mother was actually born after his mother remarried, so only Zhan Sen (Evan's father) in a mental hospital in this world has this ability. In fact, the ending of this director's version is the final ending of the original script, which makes the theme of sacrifice for love more lofty and great, more beautiful and touching. But later, because the new line company was worried that the plot and picture in this shocking ending would cause some public and public anxiety, it was finally changed to the current theatrical version when it was released.

2. The ending of the theatrical version: each grew up and went his own way, but the home movie Evan watched was the first time he saw Kelly. Back in the past, Evan scolded Kelly. He and Kelly didn't become good friends, and his mother got custody of Kelly and Tommy. Evan met Kelly in the street after work, but he didn't recognize her.

3. Another ending of the butterfly effect theatrical version: tailing (55 seconds). After Evan meets Kelly, he goes back to chase Kelly.

4. The happy ending of the abandoned theatrical version of Butterfly Effect: acquaintance (53 seconds), and the two recognize each other.
