Movie details for Memento
Because of his condition, Leonard essentially lives his life in short, present-tense segments, with no clear idea of what's just happened to him. That's where Memento gets really interesting; the story begins at the end, and the movie jumps backward in 10-minute segments. The suspense of the movie lies not in discovering what happens, but in finding out why it happened. Amazingly, the movie achieves edge-of-your-seat excitement even as it moves backward in time, and it keeps the mind hopping as cause and effect are pieced together.
Pearce captures Leonard perfectly, conveying both the tragic romance of his quest and his wry humor in dealing with his condition. He is bolstered by several excellent supporting players, and the movie is all but stolen from him by Pantoliano, who delivers an amazing performance as Teddy, the guy who may or may not be on his side. Memento has an intriguing structure and even meditations on the nature of perception and meaning of life if you go looking for them, but it also functions just as well as a completely absorbing thriller. It's rare to find a movie this exciting with so much intelligence behind it. --Ali Davis
