Memento
This movie is not talked abt enough. I love non linear storytelling, and this film is one of the best of its type. The film is 90% of u trying to figure out what the hell happened, and only at the end do u figure a sliver of it out. A masterpiece in storytelling, this is such a thrilling film to watch. Before shutter Island, there was memento.
This might be one of Nolan's greatest films.
