The opening sequence throws the audience straight in to the action. there is a close-up of one of the characters faces then she falls off a bridge. I think that is very interesting, as it hints at the narrative.

It starts in a non-linear structure as the audience are thrown into the middle of the film. This makes the audience want to know what happened before they got up to this point. I however did not really like this technique as I felt I couldn't get a grasp on the film.
