Factual error: The Sanderson House had been turned into a museum complete with a gift counter. The museum had been closed for years (note the dust and spider webs). The fluid in the lighter max gets would have evaporated after a few months as Zippos are not airtight like a plastic disposable lighter would be.
Other mistake: When Mary goes to save Winifred, there is no cord coming from the Hoover. However, next scene shows Dani, Allison and Billy grab a medium sized cord. Next scene then shows the cord much much much bigger.
Factual error: Binx is shown pouring hot liquid from a cauldron that is over a flame, the iron would be too hot for him to touch without getting burned.
Other mistake: After the Sanderson sisters are done sucking the life out of Emily Binx, they do a little dance thing after they become younger. When either Winifred or Mary swings past her, Emily's leg moves even though she's supposed to be dead.
Continuity mistake: There is a scene when Max and his girlfriend are awakening from their slumber to a room filled with early morning sunlight, but when they open Winifred's magic book, and the beam of light shoots from the rooftop, it is clearly still before dawn.
Continuity mistake: At the beginning of the movie, after the witches suck the life out of Emily, Winifred looks in a mirror and says, "Well . . . younger," and her green jacket, with a hood, is on her. In the next shot, when she says, "But, it's a start," she is not wearing her jacket at all.
Factual error: Just after the towns-people have hung the three witches, you can see the executioner walking away. They outfit he is wearing is leather and has some sort of metal spikes on it. This outfit is too modern for that particular time.
Continuity mistake: When Winifred turns to stone in the graveyard, her fingernails rip shreds of cloth off of Max's sweatshirt (you can see them when he falls). Exactly one minute later, when he is lying down next to Dani and talking to her, it is clear that his sweatshirt is merely ripped, not shredded.
Continuity mistake: When Max and Allison rescue Dani from the witches' house, they turn on the car lights to trick the witches into thinking it is daylight. After they get in the car and drive off, the same light that was supposed to have come from the headlight is still shining after they have left.
Other mistake: In the first graveyard scene, when Allison swats a tree branch at Sarah, Sarah yells, "Ouch," and flies away but the branch never touched her.
Continuity mistake: When the witches take Dani back to the museum, the rope they use to tie her up with changes from shot to shot. First it's up around her neck, then it's around her chest.
Continuity mistake: In the last scene in the graveyard, when Max is glowing and hanging off of Winifred's broomstick, his hands constantly go from a far to short distance away from the end of the broom between shots.
Continuity mistake: When the parents are at the party, Dani & Max's mother puts her hands up while she is dancing and you can see her wedding ring. But when the camera cuts to Dani and then back to her again, the ring is gone.
Other mistake: At Allison's party after she gets Max and herself a drink. One shot shows her going to take a drink, but next shot from behind she takes up the cup again and drinks.
Continuity mistake: In the scene just after Max summoned the "burning rain of death," when they're in the graveyard, Max's hair and jacket are completely dry after he was soaking wet only five minutes prior.
Other mistake: At the beginning of the film, Winifred's lipstick is small and in the middle of her upper and lower lip. However, as the scenes progress, her lipstick is bigger and she had no time to apply more lipstick- this is before the sisters are hung.
Continuity mistake: When the Sanderson sisters get on the bus, the headlights on the bus are on because it is dark out. They are visibly on at that point and as well as when the bus runs over Binx but, when the sisters get off of the bus, the lights are not on (it is still dark out and it is only a few minutes later). If the bus was merely letting them off (which it was, it drove away a few seconds later), why were the lights turned off?
Continuity mistake: When the Sanderson sisters suck the life out of Emily Binx, when Winifred says her line, her hood is on, but when they dance in a circle it comes off by itself.
Revealing mistake: Right before the witches burst through the roof of Max's house, after they retrieve the book, you can see the charge used to set off the explosion in the window just below where they exit.
