Memento (2000; directed by Christopher Nolan): Ostensibly Memento is a film about a man with a brain injury that renders him unable to form new memories who sets out to get revenge for the murder of his wife. The protagonist of Memento relies on external resources in place of his memory to function. For instance, a file, camera, and body tattoos. Part of the sense of discombobulation that the protagonist faces is engendered in the viewer by the non-linear narrative of the film. This clever trick forces us as viewers to construct and abandon interpretations of the film as we progress through it, in much the same way that the protagonist navigates his own world. It also serves as a fundamental critique to traditional theories of mind that consider the boundaries of our minds to reside within the confines of our bodies. To my mind, Christopher Nolan’s second film is one of his most philosophically enriching. [recommended by Rupert Read, University of East Anglia]
