Continuity mistake: Anna walks up to Uncle Stepan holding a glass. She holds it with just her left hand in the wider shot, becoming two in the following, across the sentence "You have an uncle, Anna, who doesn't steal things from the dead." (00:06:00)
Continuity mistake: Anna's uncle storms away refusing to translate the notebook of the dead girl. Anna sits down while her mom lays the table. In the close-up, she has all the utensils on the cloth (she missed the spoon in the wider shot) and the knife shifted more to her right. (00:06:35)
Continuity mistake: Kiril comes out of the restaurant's back door, shouts at the dog and puts a hand on Nikolai's shoulder. He is talking across the two shots about his wife, in the second one his hand is not on his shoulder, it is on his back. (00:07:15)
Continuity mistake: During her first visit to the Trans Siberian restaurant, Semyon is walking Anna across the room. She walks along a table, and the waiters and waitresses she passes by are inconsistent between shots (for instance she walks past a woman, but in the front view there's only a man behind her). (00:09:00)
Continuity mistake: In the kitchen, Semyon is telling Anna how 'sad, very sad' is that he can't remember the woman having anything to do with the restaurant. A restaurant worker with a towel in hand walks past them, and has already opened a fridge and looking into it in Naomi Watts' close-up. (00:11:05)
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: 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: On the doorstep of the restaurant during the rainy night, a very drunk Kiril is entangled with Nikolai. He has his right arm around Nikolai's shoulder, but somehow when Anna is walking past, he's fully turned around with his left arm against Viggo Mortensen's neck. (00:24:10)
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: When Nikolai is sitting in the chair in the brothel, his jacket sleeve is pulled up to his elbow. When Kiril pulls Nikolai to his feet, the sleeve is pulled all the way down. (00:34:00)
Continuity mistake: The necklace worn by Vincent Cassel changes position on his chest during the cut when Nikolai tells him "Calm down, Kiril." (00:34:05)
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: After using the girl in the brothel, Nikolai puts money and an icon prayer card next to her. Between the 3 shots where you can see those items, the girl is not supposed to have moved, curled in her exhausted semi-fetal position, but you can see how the card, money and even the bracelet she is wearing all change position. (00:37:30)
Continuity mistake: Anna is taking loving care of Christine in the hospital room, and while she does that she is interrupted by the creepy voice of Semyon who went all the way there. The position of Naomi Watts' arm on the crib changes between shots. (00:38:15)
Continuity mistake: When Nikolai the driver goes to the burger joint to talk to Anna and her family, the latte in front of Anna's mother in the wider shots throughout the scene has the cocoa on top in a narrow circle. In the closer angles instead it's sprinkled more spread out, noticeably different. (00:47:40 - 00:49:30)
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)
Continuity mistake: Outside of the hospital, Anna finds Nikolai on her bike, waiting for her. When he sticks out his arm with the address, pay attention to the background; there's a couple walking down the pathway, and someone with a reflective vest coming from the left. Cut for a couple seconds to Naomi Watts thinking about the proposal, and the people there haven't advanced. Similarly, camera back on her, a woman is wheeled out of the door, but does not show up in the reverse shot on Mortensen, or rather, she does but only in the one that follows. (00:55:20)
Continuity mistake: In the kitchen, Semyon is decorating dessert. He orders his son to go get the brandy bottles, and he tries to deflect the order on Nikolai. When Semyon says "No, no, he stays here", there's perfect continuity in Viggo Mortensen's gesture with the cigarette - too bad that the extra in the background had already moved away from the sink in the previous shot and now she is still working on it, and moving only after a second. (01:05:15)
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)
