Continuity mistake: The position of the champagne bottle holder and the next chair changes between shots. When Michelle enters the room and the camera is placed in the bedroom, the bottle holder stands between (and somewhat behind) the chair and the window wall. When Michelle approaches the table (camera is now Michelle) the chair is between the bottle holder and the window wall. Later, at the end of the scene this changes again, depending on where the camera is. (01:19:50)
Continuity mistake: After Juno Skinner has killed her limo driver, the limo speeds out of control. There are two champagne glasses in the cup holders next to Juno, but both glasses disappear and reappear between shots while Juno and Helen are fighting each other. With the limo speeding across the bridge, it doesn't make sense that Juno's gun stays on the roof for a while. The gun should have slid off the roof when the limo banged into the guard rails. It doesn't fall off until after the limo has passed through the flaming truck wreck.
Continuity mistake: During the scene when Arnold is taking off in the harrier jet, the pilots hide behind a squad car. One pilot is holding his sunglasses. It switches angles and he no longer has sunglasses on. Then his hand moves and they appear as if they had fallen off and he was grabbing them. A few frames later they disappear again. If you look closely, it was obvious they were CGI'd in during editing.
Continuity mistake: After the Swiss scene, Harry, Albert and Faisil are in the office. Albert talks about the Chinese woman and the dozens screens behind are broadcasting news reports. When they walk away, a mere frame later, the images on the screens surrounding are completely different, now broadcasting satellite images and computer texts. (00:21:35)
