Continuity mistake: When Sandra Bullock and Nicole Kidman are getting ready to bring back Nicole Kidman's jerk boyfriend from the dead, they are going to put him on a counter that has towels and other stuff on it. The camera shows them picking him up and putting him on the counter, and when they do, the towels and stuff are all gone, without them clearing it off.
Continuity mistake: When they do the spell on Nicole's boyfriend, Nicole cuts his top, then in the next scene, it's a different, buttoned up top, not the one that Nicole cut in the first scene.
Continuity mistake: Aunt Jet picks up a broom after Sally and Gillian banish Jimmy's spirit from Gillian's body. In the next shot, where the spirit is swirling near the ceiling, she is not holding the broom but has it again in the shot following.
Continuity mistake: When Jillian is running away with her boyfriend for the first time, when they are getting ready to exchange blood for bonding, the camera cuts to her boyfriend on the ground below the deck.

Continuity mistake: When Aidan Quinn is questioning Sandra, as he is coming out of the herb house, he pulls out the letter that Sandra wrote Gillian. In one shot his hand and the envelope is facing one direction, in the next shot, they are facing a different direction.

Visible crew/equipment: In the scene with Nicole Kidman's exorcism, the camera pans to the area above the mantle, where previously the girls had been removing pictures. You can see a section of the wall, about the size of a picture, opening and banging back into the wall. It appears that they intended to hang a picture there and have it banging during the scene, but forgot to hang it up.
Continuity mistake: When Sandra just goes to her shop after staying in bed for a few days she places a bottle on the shelf, but in the next scene it's gone.
Factual error: When Sally is leaving to rescue Gilly from her boyfriend she asks the Aunts to look after her children. The Aunts then say that they will take the children with them to the solstice celebration. A few days later when the cop is interviewing Sally he gives the date as March 8th. There are two solstices each year, one in December and one in June. Since this film takes place in early March, the Aunts could not have been going to a solstice celebration.
Continuity mistake: Just before Sally and Aidian kiss for the first time, (in the bedroom) they are talking about the disappearance of Gillian's boyfriend. There's one shot where Sally tucks some of her hair behind her right ear. She leaves a clump of it in front of her ear. A shot or so later, a lot less hair is in front of her ear. Just before they kiss, the large clump is back.
Continuity mistake: When all of the women come to form the coven to drive the ghost out of Nicole Kidman, all of the women are standing holding the brooms. When Nicole gets up and rushes at them, all of the brooms are on the floor, and the women are standing back from them. Next scene, they are holding them again.

Character mistake: In the scene when Gillian and Sally are dragging the boyfriend in to put him on the table Gillian says, "Watch his balls Sal". It is in Nicole Kidman's native Australian accent and the rest of the movie she speaks with a Northeastern US accent.
Revealing mistake: During the exorcism, we see the women grabbing hands to form the circle, but it is the same three pairs of hands repeated several times, giving the illusion that all 12 women did it.
Continuity mistake: When little Sally is casting the love spell using the flower petals, she picks a flower from each plant as she lists a quality she wants in her perfect man. When it shows the bowl as she sends them into the sky, they are all the same type of white rose petal.
