Continuity mistake: In the opening scene when the priest is playing the piano, in close shots of him you can see the back of the musical sheets sitting on the piano, and they are just pages of musical notes. Yet between two shots a book which says "Eckstein" appears. Then in the next close shot the "Eckstein" booklet isn't there and just musical sheets are visible. (00:00:25)
Continuity mistake: When Father McFeely arrives at Hell House, Megan's Mother opens the door, and he walks forward and raises his hand to his hat. Then in the next behind shot his hand is down but in the next shot his hand is on his hat again, and he then takes his hat off. (00:01:55)
Continuity mistake: When Father McFeely arrives at the Hell House in the cab, the cab parks right next to a light pole. Between shots the position of the cab in front on the light pole noticeably moves. (00:01:55)

Continuity mistake: When Father Harris' lips are stuck to the crucifix he is trying to pull it loose with his right hand. When it cuts he is pulling it with his left hand. (00:04:55)
Continuity mistake: When Megan is in bed (not the vomit scene), her hands are tied. But when Father Harris begins to pray "Holy Lord. Almighty Father", it's quite obvious that Megan's hands are untied. When it cuts her hands are tied again. Her hand is also suddenly untied when she says "Your mother sucks # in Hell". (00:05:35)
Continuity mistake: After the vomit scene it cuts to Megan's mom looking up the stairs. She lifts her left arm up to her mouth, but when it cuts it's her right arm that's up. (00:06:30)
Continuity mistake: When Buddy runs up to Cindy in the school passageway with the book, you can see that it is a "windows for dummies" book (or something similar), when he hands the book to Cindy, it suddenly changes to the Harry Potter cover. (00:12:50)
Continuity mistake: During the scene where Cindy is talking to Buddy in the college hallway, her backpack straps alternate between shots. In some shots she has both straps up, and in others one strap is up and one strap is down. (00:13:00)
Continuity mistake: When Cindy is driving along, singing along to a song in her car, in wide shots of the car, you can see the road she drives down has a white fence running along both sides of the road. But in shots of Cindy in her car, a white fence should be visible, but isn't there. (00:13:35)
Continuity mistake: When Cindy is driving along, singing, both of her windows are rolled down about halfway. We can see the window next to Cindy is rolled down halfway in the first two closeups of Cindy. It then cuts to a wideshot of the car and then another closeup, and the window is now fully winded down. Cindy clearly never winds the window down, it has just rolled down between shots. (00:13:40)
Continuity mistake: In the beginning of the movie Cindy drives towards the castle and sings along with the radio. She passes (and almost hits) a car. If you look through the back window, the car never comes by. (00:14:00)
Continuity mistake: Cindy is driving to Kane Manor, and she's singing along to a song. Then the song tells Cindy to shut up. After this Cindy goes from holding the sides of her steering wheel, then the top of the wheel, then back to holding the sides between shots. (00:14:00)
Continuity mistake: For the entire movie, the main female character has a French manicure with long nails. But when they are spoofing "What Lies Beneath" and she lays her professor down on the table, she has short natural nails. (00:14:10 - 00:37:30)
Continuity mistake: When Cindy first meets Hanson, the big knife Hanson holds changes angles in his hand between shots. (00:15:50)
Continuity mistake: When Hanson drops Cindy's bag, the items on the floor change position. Also, a blue purse disappears from the floor between the shots. (00:17:00)
Continuity mistake: When Hanson takes Cindy's toothbrush, he puts it into the left side of his mouth. When it cuts, it has suddenly moved to the right side of his mouth. (00:17:10)
Continuity mistake: When the character played by Kathereen Robertson walks into the dining room and asks the guys to get her a seat, Buddy places a seat right in front of her yet in the next scene, two chairs slide up to her followed by a wheelchair and Buddy seems to have teleported into a different room altogether. (00:21:50)
Continuity mistake: When the butler (Chris Elliot) goes to bring the potatoes from the cart to the table, you can see on the left side of his face he has a small piece of potatoes there. When he goes to eat the potatoes from his hand it's gone. (00:22:45)
Continuity mistake: The amount of potatoes varies on the butler's (Chris Elliot) hand from shot to shot during the dinner scene. (00:22:55)
