Continuity mistake: Julia (Christina Applegate) puts a "Hello My Name Is..." sticker on Thibeau's tunic with her phone number on it. Only part of the sticker is visible. When he turns around to walk down the stairs, it is fully visible. A moment later when he stops the purse snatcher, it's gone. Three seconds later, talking to the woman dressed as a witch, it's back again. (00:50:15)
Continuity mistake: Right at the end, when Julia is at the castle that she got, when she is walking by the cannons you can see that she has black boots on. But in the next shot when the old man is talking, if you look hard enough in the last frame of that view, she is wearing white, high heel sandals.
