This movie is very under rated. Christopher Nolan directed it before he became very fameous for The Dark Knight. The plot is very interesting, the main character is a man who can not make new memories and has to tattoo information allover his body. The man is looking for the person who killed his wife. The movie is unique in the fact that it is backwards. When a scene ends the following scene will end upon the begining of the previous scene. I had to watch this movie a few times to comprehend what was happening.
