Memento.

The narrative structure of Memento is not like your average film, it is what you call 'non-chronological' order. This is when the film isnt in order, bits are just thrown in at certain points. but the way this film was made, is that it meets somewhere in the middle, and the start and the finish work back to front. during the film there are black and white memories. these are in the correct order, and are basically what we've just seen backwards. There are 3 main characters. Lennie, Natasha, and Teddy. Teddy turns out to be the man that hes looking for the whole way through the film, but because Lennie has a memory problem, he doesn't know that this is the man he's looking for.

Lennie is a very mysterious character, he cannot create new memories so has to go on trust. and he trust people he doesn't know, but he says he is a good judge of character and can tell when people are lying. He takes a picture of all places and people he has been in contact with, and writes a little message on the back, and for him to find out something about someone or something, he'll just look at his photo, and believe his own hand writing. he also gets important facts tattoo'd onto different parts of his body. and more of them are revealed as the film goes on. Because Lennie cannot create new memories, he cannot learn to trust people. so the film ends up with him going crazy, not believing a word people say. even if they are trying to help him.
