Memento ending explained: what Leonard learns and chooses to forget
Spoilers ahead: this article discusses the ending.
Memento ending explained starts with a simple fact: the last scene in the film is the earliest point in the story, and the first scene is the last. Christopher Nolan's 2000 thriller follows Leonard Shelby (Guy Pearce), a man who cannot form new memories, as he hunts the man he believes killed his wife.
The ending reveals that Leonard is not just a victim of his condition but someone who uses it. To understand that, you first need to know how the film is built.
How Memento is structured
The film alternates between two strands. Black-and-white scenes run forward in time and show Leonard in a motel room on the phone. Colour scenes run backwards, each one ending where the previous one began, so the viewer shares Leonard's confusion about what just happened.
The two strands meet at the end. The transition happens as a Polaroid develops and the image turns from black and white to colour. At that moment the story's beginning and end click together.
What Teddy tells Leonard
In the final colour scene, Leonard kills a drug dealer called Jimmy Grantz, believing him to be John G. Teddy (Joe Pantoliano), a corrupt cop, arrives and tells Leonard the truth as he sees it. Leonard already found and killed the real attacker more than a year earlier, but he does not remember it. Since then Teddy has been pointing him at other targets who fit the clue.
Teddy also claims that the story of Sammy Jankis, the insurance client Leonard says accidentally killed his diabetic wife with repeated insulin shots, is really Leonard's own story. In this account Leonard's wife survived the assault, and it was Leonard who gave her the fatal overdose.
Memento ending explained: Leonard's choice
This is the heart of the Memento ending explained. Leonard burns the photos of Jimmy's body and of his earlier revenge. In a monologue he admits he is willing to lie to himself to be happy and to believe his actions matter. He then writes down Teddy's licence plate as the next fact to have tattooed and notes that Teddy cannot be trusted.
That note leads directly to the film's opening scene, where Leonard shoots Teddy. The man who has spent the film searching for the truth turns out to have built his own trap knowingly, choosing a purpose over peace.
Is Teddy telling the truth?
The film never confirms it. Teddy lies throughout the story, and Leonard insists his memories from before the attack are intact. Nolan has said audiences tend to trust Leonard's photo of Teddy over Teddy himself, and that the one character who could know the truth is also the least trustworthy. He called that idea very frightening.
Many viewers read the Sammy story as Leonard's repressed memory of what he did, but the film keeps the door open on purpose.
- Teddy is right: Leonard killed his wife and rewrote it as Sammy's story.
- Teddy is lying: he wants Leonard to stop asking questions about Teddy's own role.
- Both: Teddy mixes truth and manipulation, and Leonard can never sort one from the other.
Where the story came from
The film is based on Memento Mori, a short story by Nolan's brother Jonathan, published in 2001. Its hero, Earl, is in a mental institution, and unlike the film the story leaves no doubt that he finds and kills his wife's killer. Several American distributors turned the film down as too confusing; it went on to earn Oscar nominations for its screenplay and editing.
Questions people ask
Who killed Leonard's wife in Memento?
Leonard believes an intruder did. Teddy claims the attacker only injured her and Leonard later killed her with an insulin overdose. The film does not confirm either version.
Is Sammy Jankis real?
Teddy says Sammy was a con man without a wife, and that Leonard projected his own story onto him. The film leaves it uncertain.
Why does Leonard kill Teddy?
Because the Leonard of the ending deliberately leaves himself a clue that makes Teddy the next John G., choosing a target over the truth.
Why are some scenes in black and white?
They run in chronological order, while the colour scenes run in reverse. The two meet at the end.
