How does the timeline in memento work?
Quick Answer
Memento tells its story in two interwoven timelines—black‑and‑white scenes that move forward chronologically, and color scenes that move backward—meeting at the film’s ending.
Explanation
The film is divided into 12 short scenes, each labeled with a timestamp. 6 of them are shown in black and white, running in chronological order from the beginning of Leonard Shelby’s quest to the end. The other 6 are in color and are shown in reverse order, starting with the final moment of the story and moving backwards. By alternating between the two, the audience experiences the narrative from Leonard’s perspective of memory loss and gradually reconstructs the entire story in a way that mirrors his fragmented recollection. The convergence of the two timelines at the film’s climax reveals that the seemingly inevitable ending was actually produced by a deliberate manipulation of memory, underscoring the theme that memory can be as unreliable as time itself.
