In Christopher Nolan's tricky, time-jumping thriller, an insurance investigator by the name of Leonard (Guy Pearce) tries to find his wife's killer, but is hampered because an injury he suffered in the attack left him with anterograde amnesia and without short-term memory. Using photos, notes, and clues tattooed onto his body, Leonard frantically tries to identify the murderer, and, at the same time, figure out what part a self-professed close friend (Joe Pantoliano) and a barmaid (Carrie-Anne Moss) play in the mystery. 113 min.
