Continuity mistake: During the chase scene in the tunnel, the two motorcycles were always pretty close to each other through most of the scene. When the first motorist was knocked off, it should've taken out the second one right away. (01:36:00)
Continuity mistake: When the kid has thrown the ball on the thug kid, you see the thug stumble forward. When it cuts he stumbles again. (00:31:20)
Continuity mistake: In the first heist we see a quick shot of the garbage men getting into position followed by a shot of John and Charlie in the water moving some of the gold. In the shot of John, the way he holds the current gold bar changes between shots. (00:14:40)
Continuity mistake: A scene in the junkyard, near the middle of the film, the Ukrainian gang's black Cadillac Seville is shown entering the location. However. In the next shot, the car has suddenly changed into a black Cadillac CTS. (00:50:00)
Continuity mistake: The weather changes between the first two scenes in Venice. The scene in St. Mark's Square is in fog, mist and rain, but in the next scene, supposedly taking place at exactly the same time (with Handsome Rob) there are blue skies.
Continuity mistake: When Rob gets the key off Becky, a camera man's shadow can be seen moving over the bed. This is not Rob's shadow as at the time he isn't moving. (00:43:20)
Continuity mistake: When Wrench first sees Stella, the neck cover on his welder's mask is loose. The camera cuts and it's not tucked behind his head.
Continuity mistake: In the subway, all the Minis get covered in dust and grime. However, while the red and white ones stay fairly dirty, the blue one becomes spotless when he is facing off against Steve's helicopter.
Continuity mistake: After the heist, the blue Mini is seen to have a dent in the rear wing. Throughout the chase, up to when the helicopter hits the blue Mini, the dent changes size constantly.
Continuity mistake: When Charlie is a kid, a kid knocks another kid's book out of his hands. The book hits the lockers and one of the lockers swings open. When it cuts, the locker is closed again. (00:31:20)
Continuity mistake: When Charlie and Stella are talking in Stella's hotel room in Hollywood, a strand of her hair goes from over her head to hanging beside her face as the shot cuts to behind her. When it cuts to her face, the strand is over her head again, though she didn't touch her hair.
Answer: The Mini Cooper for the movie was also made as an electric car for the chase scenes in the tunnel because gas-powered cars were not allowed to be used in the tunnels. I heard that from the director's cut.
