This isn't a thriller in the American sense of the term. It certainly has more in common with meticulously paced French thrillers, which were as much character studies as they were genre pieces. Director Anton Corbijn has no intentions of making this film for the ADD crowd accustomed to lightning fast editing and adrenaline-fueled action sequences at regular intervals. He is certainly asking his audience to be patient.
Jack, or Edward, (we're really not sure which name is true) (George Clooney, SYRIANA) is a master assassin. He's as cold and remote as the wintery mountain setting the film begins in. He is being hunted by Swede assassins. His handler Pavel (Johan Leysen, BROTHERHOOD OF THE WOLF) says he is slipping and needs to lay low. He doesn't like the safe house set up for him, so he changes the plans. One might expect this to really piss off his boss, but Jack is the best at engineering weapons to precise specifications and Pavel has a new client.
