Adapted once before, in a drab 1988 made-for-TV miniseries starring Richard Chamberlain, the Ludlum novel serves only as loose source material. Ludlum, who died last year, was the master of pretzel-logic thrillers. Here, the filmmakers have untangled the knots and dangled the novelist's hero from a long, straight rope.
The film begins as Jason Bourne (Matt Damon) is being pulled from the Mediterranean Sea by fishermen who mistake him for dead. He is, in a sense: Bourne, or whatever his name really is, has no knowledge of who he is or what he does. He lacks identification, save for two bullets in his back and a laser device embedded in his hip that reveals the name of a bank in Zurich and an account number.
The audience, however, knows immediately who he works for and what he's up to: We're introduced to Conklin (Chris Cooper), a gruff CIA boss (and modern-day cinema's oldest prototype, the malevolent government stooge) prone to barking short, sharp orders ("Get it done!" "Get everybody up!" "Work it!"). Conklin has botched an assassination attempt on an exiled rebel leader (Adewale Akinnuoye-Agbaje, Oz's Simon Adebisi) who is threatening to out the CIA and its dirty work. Bourne was the operative in charge of the hit, and now he's presumed dead or dirty. The rest of the film is little more than a chase. Bourne and his reluctant passenger, Run Lola Run's Franka Potente, try simultaneously to elude Conklin and his cronies and figure out just who the hell he is.
The first scenes in which Damon struggles to remember his identity are well-played. He asks himself who he is, over and over, in various languages (French, German), and the questions roll from his tongue in such a way as to suggest he doesn't even realize he's not speaking English. He's lost his name but not his identity; if he doesn't know who or quite what he is, he at least knows what he is capable of. Damon looks lost and dazed but never frightened, as though somewhere in Bourne's broken mind, he retains fragments he's actually trying to forget. In the film's earliest scenes -- on the fishing boat, in a speeding train -- Damon never catches a clear glimpse of himself. In the reflections from a grimy mirror and a train window, he's fuzzy, distorted -- a man who can't even tell what he looks like. When he does realize he's an assassin, he's disappointed and even ashamed; amnesia, once more, renders the nasty man compassionate.
Save for two action sequences so outrageous the apologist is tempted to dismiss them as parody, The Bourne Identity almost feels as though it were filmed in slow motion, yet it never drags. In no hurry to conclude its pursuit, even a car chase through Paris plays measured, leaving only dents and thuds instead of crashes and flames. And the considered pace serves to bond Damon and Potente, who say little to each other -- that she's merely with this man implies extraordinary trust -- yet become lovers long before they fall into bed. In one scene, he dyes and cuts her hair to disguise her, and when they finally kiss, it seems oddly redundant.
The filmmakers never feel the need to fill in the blanks, not even Bourne. They hint at things -- why, for instance, an assassin abhors guns -- without being explicit. That makes it not only an exceptional thriller but a transcendent summer movie: It assumes, for two hours, you've brain and heart enough to stick with a film that doesn't condescend, doesn't beat you up, and doesn't dumb you to death.
