One of film director Christopher Nolan's earliest movies has since become a classic in its genre.
Possibly better known for his directorship of several of the recent Batman adventures, Nolan's wonderful 2000 film Memento is based upon a short story written by his brother, Jonathan.
It stars Guy Pearce as a man suffering from anterograde amnesia, following a burglary in which his wife is raped and murdered. His condition, a result of head trauma during the attack, means that he is no longer able to create new memories. In his search for the man who he is convinced is responsible for his wife's death, he creates a system which allows him to recall people and events.
