CIA-trained killer Jason Bourne is still in search of his identity in The Bourne Ultimatum. The third instalment in the amnesiac's saga whisks us through Moscow, Russia, Turin, Italy, Tangier, Morocco, and New York, unspecified. Early on it plunges breathlessly into a cracking action sequence in rush-hour Waterloo (London, England, not Belgium) as CIA operatives try to foil a meeting between our hero and Fleet Street's finest. This is The Guardian's security correspondent, who, given that he fails to notice a passer-by dumping an alien mobile phone in his pocket and panics at the sight of a litter-collector, may have made an unwise career choice. Or so our hero suspects, to judge by his snarl of "This isn't a story in a noospaper - this is real", a nice distinction. It doesn't prevent the Guardian man being shot, a victim of London public transport's notorious overcrowding.

Director Paul Greengrass piles on the action at a breathless pace, which perhaps fortunately leaves no time to think. Matt Damon has matured impressively as the agent struggling to fill in the gaps between hazy glimpses of his murderous past. David Strathairn makes a superb villain in the heart of the CIA. Albert Finney is the no-neck monster scientist who, it transpires, created Bourne the killer. A rattling yarn exuberantly told, crunchingly violent but not too sadistic, give or take the odd Guardian journalist.
