Continuity mistake: During the car trip to Kansas City, Alice and the mother are both on the driver side of the car, the mother driving, and Alice in the back seat. When the mother asks Alice how her book is, there are just open fields out the window of the mother. But in the cuts to Alice, there are telephone poles going by that are not seen in the shots of the mother.
Continuity mistake: After escaping the cellar, Jennifer and Sally approach a couple from the dark. Jennifer is holding wounded Sally up on her left shoulder and holding the dead cop's pistol in her right hand. It cuts to the guy saying "What the...?" then back to the sisters, and suddenly the pistol is gone from her hand and tucked into the front of her pants. There was not enough time during the shot on the guy for her to have one handedly put the gun down the front of her pants.
