It's one of the most mind-boggling films to come from Christopher Nolan, and it turns out that real-life experience may have helped an actor in Memento in his role in the film.

The film has become widely acclaimed for its clever use of broken-up storytelling and displaced timelines to show the fragmented memory of the main character.

The 2000 flick follows Leonard Shelby (Guy Pearce), an insurance investigator, who suffers from anterograde amnesia and uses notes and tattoos to hunt for the man he thinks killed his wife, which is the last thing he remembers.
