Memento (2000)

Memento is a 2000 American neo-noir mystery 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. Starring Guy Pearce, Carrie-Anne Moss, Jorja Fox and Joe Pantoliano, the film follows Leonard Shelby (Pearce), a man who suffers from anterograde amnesia—resulting in short-term memory loss and the inability to form new memories—who uses an elaborate system of photographs, handwritten notes, and tattoos in an attempt to uncover the perpetrator who killed his wife and caused him to sustain the condition.
