Identity is a 2003 American slasher film directed by James Mangold, written by Michael Cooney, and starring John Cusack, Ray Liotta, and Amanda Peet with Alfred Molina, Clea DuVall, and Rebecca De Mornay.

Inspired by Agatha Christie's 1939 whodunit And Then There Were None, the film follows ten strangers in an isolated hotel, who are temporarily cut off from the rest of the world and mysteriously killed off one by one. Several events which take place in the hours before the characters' arrival are introduced at key moments in the film using reverse chronology structure and, in a parallel story, a murderer awaits a verdict at a crucial trial that will determine whether he will be executed for his crimes.
