Continuity mistake: At the beginning and end of the film, there is a narration who the subtitles label as Sitka, but at the very beginning, we see that the narrator is actually Denahi.
Factual error: At the beginning of the film, after Eris gives her speech, we zoom in on a map of the Eastern Mediterranean - and the island of Cyprus is conspicuously missing (it's large enough to be seen on the map).
Continuity mistake: When Donnie steals Chuckie's clothes and glasses, Chuckie puts on Donnie's shorts and complains about his eyesight. But later in the movie, when he doesn't have his glasses, it seems he can see just fine. Then, when he gets his glasses back, he says something like "I can see again."
Continuity mistake: Nino gets trussed up in silver duct tape. The boy gets bundled over the shoulders of one of the bad guys, and you can see that there is only a small amount of tape around his legs. They go straight inside the meat packing factory and suddenly in the next shot, there is a huge amount of tape around the boy's legs.
Audio problem: When Galleria is playing the piano by herself at school, it's obvious she really isn't playing. Her hands are moving way too slow for some of the parts and at the end, her hands are playing very low on the bass notes when the notes heard are in middle-low C range.
Continuity mistake: In one scene, Rabbit picks three flowers. In the next shot, Rabbit gives all of the three flowers away and still has one for himself without ever having gone back to the bush to pick one more for himself.
Other mistake: Marian asks Winthrop to go pick up a book called "The Indiana State Educational Journal 1901-1910". When we see her reading the book, it actually says "The Indiana State Educational Journal 1890-1910". (01:08:25 - 01:13:50)
Factual error: When both Erica and Courtney are racing, you can see mountains in the background, although there are no mountains in Houston, their hometown.
Continuity mistake: In the beginning, the black sheep falls backward into the fence, and the other sheep laugh. Then the angle changes, and he's about three feet from the fence. He didn't move, and he's still in the same sitting position he was in before.
Continuity mistake: Before beginning her ballet lesson, the Queen uses magic to transform both Odette's and her dress into tutu-style dresses. After Rothbart kidnaps Erasmus, the queen loses her powers before she could save him. Later on as they approach Rothbart's castle, the Queen's dress is full length again despite being unable to use magic to change it back to normal.
