Continuity mistake: When Jason lunges at Batman with his knife, there is a pile of garbage by the wall where he lands. In the first shot the barrel by the garbage is wooden. But in the next shot it's suddenly a metal barrel/drum. It then changes back to a wooden barrel again. (00:04:20)
Continuity mistake: When Butch is talking to Dawn in his room, he puts on his headphones and begins talking to some unknown being and seems to be in a trance. His head is resting flat on his pillow as he grabs Dawn's arm. Just after she pulls away, Butch's hand is in the position as if he was still holding her. However his head is now resting up on the headboard. He couldn't have propped himself up with his hand in that position, especially in the matter of a few seconds. (00:40:40)
Continuity mistake: In the basement when the girls are talking, one mentions to Chloe that she and Carl would make an adorable couple. Chloe's left arm is stretched up above her head in this shot. But in the next shot when she corrects her on the guy's name, it's suddenly down by her lap. (00:06:10)
Continuity mistake: Mrs. Marsh carries two plates with food to the table and starts to place the plate in her right hand in front of Mr. Marsh, but when the camera shifts, she is placing Jonathan's plate in front of him (and it appears she is doing so with her right hand, not the left hand she was holding Jonathan's in). (00:35:54)
Continuity mistake: Just before the Paratroopers are about to make the jump on D-Day, they hook up their static lines, including Boyce. When Boyce is pushed out of the aircraft by Ford, his static line is stuffed to the back of his parachute.
Continuity mistake: When Rita is running toward the hanger in a scene that mirrors the first film, she is running on a long wood walkway. In the next shot however, she is on the dirt.
