Continuity mistake: In the final battle scene between Geena Davis and Craig Beirko, Beirko's character slashes Davis' character across the stomach (upper right hand side). In the next shot, the wound is located on the lower left side and in a subsequent shot, the wound has multiplied to become two wounds: one in the upper right hand side and a second in the lower left hand side.
Continuity mistake: When Geena Davis is ice-skating with her daughter, she takes off her right glove to hold the girl's hand and help her up. The glove is still off when she says "3 2 1, Go." but when the camera changes point-of-view in the next shot, the glove is somehow back on her hand again. (00:19:00)
Continuity mistake: Geena Davis has her hands and feet tied to the water wheel when she's being tortured for information. Under water she manages to free one of her hands but not her feet, when she comes up for air and shoots her captor, she drops the gun and unties her other hand, but her feet are still tied, so she would have fallen face first into the water.
Continuity mistake: When Geena Davis is underwater by the water wheel, she notices that the dead body down there has a gun and she starts to reach for it. Then in the next shot, we see her reaching hand holding on to the water wheel but she still looks like she's reaching for the gun even though she's holding on to the wheel.
Continuity mistake: When the man who was holding the carollers hostage comes to Davis', she dives behind the fridge door, the man shoots the door and Davis flies backwards. After he kicks the door shut, there's not a scratch on it.
Continuity mistake: At one point during the fight scene between Sam Caine and the intruder, they fight over a shotgun. When they both fall over the shotgun disappears. A sound effect of the gun falling to the floor is even inserted to cover up the fact that the shotgun just vanishes.
Continuity mistake: When Sam Caine teaches her daughter Caitlin how to ice-skate, Caitlin is pushed but falls on her knees. In the next shot, she somehow lands on her butt.
Continuity mistake: When Waldman is telling his wife Alice how disgusting her dog is, the way he holds his spoon keeps changing between cuts.
