“Memento (2000)” is a psychological thriller directed by Christopher Nolan. The film tells the story of Leonard Shelby, portrayed by Guy Pearce, who suffers from short-term memory loss following a traumatic incident. Leonard is unable to form new memories and relies on Polaroid photographs and tattoos on his body to piece together clues about his wife’s murder. The narrative is presented in a non-linear fashion, alternating between black-and-white sequences shot chronologically and color sequences that unfold in reverse order, mimicking Leonard’s fragmented memory. As Leonard navigates through a world of deception and uncertainty, he grapples with the reliability of his own recollections and seeks vengeance against those he believes responsible for his wife’s death.
