Recent TV spots would have you believe Anton Corbijn’s The American is a slam-bang actioner, one in the style of The Bourne Trilogy. Such a campaign is doing the movie a disservice. There are moments of violence, but Corbijn and screenwriter Rowan Joffe focus more on behavior than action. In fact, those expecting thrills will be put off by the movie’s slow-burn intensity, as well as its frequent moments of tense silence. It’s a shame, really, for there is plenty to relish, including George Clooney’s best performance since Michael Clayton.
