Memento

Memento is a 2000 American neo-noir psychological thriller film written and directed by Christopher Nolan, based on the short story "Memento Mori" by his brother Jonathan Nolan, which was later published in 2001. The film stars Guy Pearce as Leonard Shelby, a man who suffers from anterograde amnesia, resulting in short-term memory loss and the inability to form new memories. He searches for the people who attacked him, raped and killed his wife, using an elaborate system of Polaroid photographs, handwritten notes, and tattoos to track information he won't remember. Carrie-Anne Moss and Joe Pantoliano co-star in the film.
