Corrected entry: Just after the towns-people have hung the three witches, you can see the executioner walking away. The outfit he is wearing is leather and has some sort of metal spikes on it. This outfit is too modern for that particular time.
Corrected entry: When the Sanderson Sisters first return to the house, Sister Sarah reaches up and finds her lucky rat tail just where she left it. It's been 300 years; the rat tail would have decomposed in that amount of time. It has been suggested that since she is a witch, she could have put a resistant spell on it. But we did not see her do that in the movie, and if we do not see it, we cannot use it to explain away the mistake. That "logic" could be used to explain away many of the mistakes caught by the audience.
Corrected entry: After Max has drunk the potion at the end of the movie, he and Winifred Sanderson are fighting in the air and then both fall into the cemetery. However, the cemetery is hallowed ground, and according to the beginning of the movie, the Sanderson Sisters should technically not be able to set foot on the grounds.
Corrected entry: In the scene where Max lights the black flame candle and the Sanderson sisters return from the dead, Dani tells the sisters she lit the candle. However, later in the graveyard Sarah Sanderson calls Max the virgin who lit the candle. She could not have known it was Max and not Dani who lit the candle.
Corrected entry: Max just moved to Salem and all throughout his house we are shown stacks of cardboard boxes, indicating that this is the case as well. One problem: Max's room has no boxes whatsoever, and is completely unpacked, yet he was attending school, and would have had the least amount of time to unpack of the whole family, not to mention he is the only member of the family who is against moving there.
Corrected entry: After the game sunrise scene, as the Ford Explorer screeches to a stop outside of the cemetery gates you can see it has California license plates, not Massachusetts.
Corrected entry: Just before The Sanderson Sisters put the two bullies in the cages, the blonde boy says, "why is it always the ugly girls out late?" In the background you can see a crew member run out and adjust something on the lawn.
Corrected entry: Throughout the movie, Binx the talking cat speaks with a British accent. The movie is set in Salem, Massachusetts. I know he is supposed to be from 1693, but I don't think many Americans were speaking with British accents. Even if he was originally from England, I'm sure after 300 years he would lose his accent. But seeing his father at the beginning of the movie spoke with an American accent, I doubt he's from England. So where did the accent come from?
Corrected entry: At the beginning of the movie, Max's teacher tells the class the story of Binx and the Sanderson sisters (shown as a flashback). Later, Allison talks to Binx and says, "so the legends are true." If no one ever knew what happened to Binx, how did the story get passed down in the first place?
Corrected entry: Thackery Binx switches between a British accent and an American accent throughout the movie.
Corrected entry: The zombie gets his fingers chopped off by the motorcycle but he is never shown missing fingers at any time in the movie.
Corrected entry: In the end when they are all in the cemetery, Binx jumps on Winnifred and she drops the potion. When she drops it, Max lunges to catch it. Why didn't he just let it drop and smash? He would have saved his sister's life and he wouldn't have had to risk his life by drinking the potion himself.
