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 cape with a hood is on her in the closeup. In the next shot, when she says, "But, it's a start," she is not wearing her cape at all. (00:07:00)
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? (00:48:06)
Continuity mistake: After Winifred, Sarah, and Mary get off the bus, when the young girl dressed as an angel stops and says, "Bless you," the candy bag she's holding switches from her left hand to her right arm, then back to her left hand, between shots. (00:48:10)
Continuity mistake: When the parents are at the party, Dani and Max's mother puts her hands up while she is dancing and you can see her wedding ring in the shots facing her, but in the shots facing Dani the ring is gone. (00:55:20)
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. (01:28:35)
Plot hole: After Max and Allison rescue Dani from the witches, Max is driving his parents' car. Winifred flies up along side of them and asks Max to show her his driver's permit. How would she know about driving permits, since she's been dead for 300 years?
Suggested correction: There is a lot the movie doesn't show us about who they've passed and what they heard all evening. One example being we don't know everything the bus driver said to them. It's perfectly reasonable they heard somebody make reference to a driver's permit and the movie did not show us this conversation deeming it invalid to the plot.
Not referring to a learner's permit. She would have known what it means. She's emulating a cop pulling him over. She would have to know what that means...and know the difference between a license and a learners permit. Enough to find it funny and relevant to the situation.
Factual error: Zippo lighters are sold dry, no fluid when new.
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. She's also playing with her hands and bobbing her head.
Factual error: The film is set on Halloween (31st October) 1993. At the start of the film, Max is shown at school on Halloween. However, Halloween 1993 was actually a Sunday.
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.
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: 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.
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.
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.
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.
Other mistake: At Allison's party after she gets Max and herself a drink, one shot shows her going to take a drink but in the next shot from behind she takes up the cup again and drinks.
Continuity 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 Dani and Max wake up, the sun is out, and they say it's "5:00am," but when they go upstairs and Dani is caught, it's dark outside again.
Continuity mistake: In the grave yard, Binx is sitting on the book so Winnifred can't get it. A second later after their exchange, the cat is suddenly missing.
