Memento (2000) - Trailer
The plot is narrated in two directions: a normal white and black story and a color story that is followed by a "backwards" passage of time. Two "clash" stories at the end of the series create a unified story. The film features actor Guy Pearce as Leonard Shelby, a patient with short-term memory loss and cannot recall new events occurring in life. He used notes, tattoos and instant photographs to save events to help him continue to live when they were forgotten. In the beginning of the series, which was actually the end of the plot, Leonard killed Teddy (Joe Pantoliano) in retaliation for the death of his wife Leonard (Jorja Fox) based on the instruction of Natalie (Carrie-Anne Moss).
