 * When Emily reverses into Tidmouth Sheds, the berth next to James is empty, but in the next shot Henry suddenly appears in it.

 * In one of the close-ups of Gordon and Emily near the end, the Christmas lights at the sheds are missing.
 * In the Latin American dubbing, due to an error when Edward says "Where are all our lights?" Javier Olguín says that line instead of Herman López.
