Continuity mistake: When the strays are scuffling with one another below the houseboat's deck, Fagin appears through the swinging doors holding a box of dog biscuits in his hands. Both of the doors are in an obvious state of disrepair, with hinges barely attached to the frame. But two shots later, the doors have somehow fixed themselves. (00:17:35)
Continuity mistake: After Oliver and Tito jump onto Jenny's limo, it makes a left turn at the intersection. Here we can see how the limo has a pair of windows on either side, but instead three windows are visible from the interior one shot later where Jenny reads a letter from her parents. In addition, the limo has gained a sunroof between shots. (00:29:45)
Continuity mistake: While talking to Sykes on the pier, Fagin falls into the water. As he walks back inside, water is dripping from his hair and clothes. He then sits in a chair, but there is no water on the floor where he has walked.
