I also quite liked this piece in Rolling Stone on the return of the Bourne franchise. I've always liked the sleeping assassin genre. The first line of Without Warning is a nod to it. The Bourne films are the apotheosis of that particular literary trope – although Robert Ludlum would hardly literary.
This piece by David Fear is worth a read for any fans:
No one knew that the War on Terror was just around the corner while folks developed the blueprints for the Bourne movies in the early aughts, or that the talented lad who cried in Robin Williams' hairy arms had an inner MMA fighter lurking within. Play poker against an Oreo-licking, scenery-chewing John Malkovich? Totally. Sweep the leg of a guy with a machine gun who just crashed through a window, crack his limbs and stab the dude with a pen? Did not see that coming.
That's the Identity scene that really sells the idea of Damon as an agile action hero — or more specifically, that his lean, mean, government-trained killing machine could be the template for an entirely different type of action-movie hero, one more suitable to the moment than the traditional steroidal he-man. The Stallone/Schwarzenegger model wasn't necessarily going to cut it now, nor, for that matter was a dapper agent with a martini in his hand and witty quip on his lips. (To say that the Bond films changed tact, and wisely so, would be an understatement.) What was needed was someone espionage-savvy who played dirty in a dirty-bomb age even if he seemed as superficially whitebread as a Midwestern all-state wrestler. Someone smart enough to have read a book and lethal enough to then use that same book as a weapon.
