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)
