Continuity mistake: Anna brings Semyon only copies of the original diary. The sheets are held together by handbag clips, which are closed in the close-ups, and open in the views from her angle. (00:23:00)
Continuity mistake: During the banquet, Semyon motions to the waiter that offers to pour him champagne, to serve the guest to his right instead. The bottle was showing the label to the camera, but in the new shot it made a 180° turn, the label faces the waiter instead. Moreover, the waiter exits left but is walking right behind Semyon right a split second later in the reaction shot as Semyon looks at his son answer the phone. (00:15:10)
Continuity mistake: Viggo Mortensen is preparing to cut off the fingers of the cadaver. He flips his tie over the shoulder in the close-up, but in the following view of the room with Cassel patting his ass the tie is down his chest again. Goes back over the shoulder for more close-ups. (00:20:05)
Continuity mistake: Kiril and Nikolai hug in the wine cellar. There's a constant back and forth between two angles where Vincent Cassel's hand is positioned differently, either on Mortensen's back, or shoulder. (01:08:40)
Continuity mistake: At papa's personal brothel, Kiril cups Nikolai's chin telling him how he wants to make sure he's "no queer." When Cassel is from the front, he's pointing his index finger under Nikolair's chin, while in the front views of Viggo Mortensen's face, Cassel gets awfully creative with the appraisal of his buddy's manliness, doing things like thumbing the cleft of his chin or using his ring finger instead. (00:34:45)
Continuity mistake: Nikolai gets hurt for the first time (slice across the chest, shown in a close-up) by one of the hitmen. He punches the aggressor in the face, who bounces against the wall. His hand is in plain view and there's no weapon. Next shot, he's brandishing the knife, and drops it only a moment later. (01:17:55)
Continuity mistake: The Chechen brothers approach Nikolai in the sauna. Viggo Mortensen has a towel draped across his back, with an irregular profile, covering the right shoulder more than the left. After a brief cut on the hitman preparing his knife, there's a close-up of Viggo, with the towel neatly arranged and properly balanced. (01:17:45)
Continuity mistake: The corpse is examined by the police; the corpse is shown once in its entirety. The knee is exposed. When Donald Sumpter inspects the body, he has to roll up the pants for the knee to be visible. (00:29:20)
Continuity mistake: Anna storms out of the burger place to talk to Nikolai. For the greater part of the scene, when the camera is on Naomi Watts her hair is nice and tidy, while in the reverse shots on Viggo Mortensen, the wind messes up her bangs. (00:49:45)
