Bourne is back. Or maybe it’d be more accurate to say that he never really went away, as this film picks up even before the second in the series, The Bourne Supremacy, has finished. So it is worth your while making sure you’ve seen that before you take a look at this one. That being said it isn’t vital, you’ll pick up on a main plot soon enough, and while what you miss out on does add to the film it isn’t totally necessary as there is plenty of back story floating around in this film.
