Continuity mistake: When Sister Irene's habit is ripped at the back, you can see a bra strap on her left shoulder which disappears when she is seen at the front and when the camera is closer to her back (when she has the pentagram carved into her).
Continuity mistake: At the beginning of the movie, the teacher asks "Has Nicky's mom volunteered?" The guy answers "Emily?" with his arms down his hips, but he had his arms folded across the chest just in the previous shot. (00:03:50)
Continuity mistake: Peter dives through the window of the attic, shattering it with shards of glass and window frame busting out and falling with him. When the camera pans down to him lying on the ground, there isn't a single shard of glass or piece of frame seen anywhere. (01:56:10)
Continuity mistake: When Buster is shot, his hat with the hole in it disappears.
Continuity mistake: When the singer hits the priest with a bottle and leaves him unconscious, she rushes outside and almost immediately witnesses the FBI guy being shot. Yet in a previous scene the priest is with the hotel worker for a significant amount of time before they also witness the murder.
Continuity mistake: Nicke enters the room to execute a Yakuza after a woman cuffed both his wrists. When Nick shoots the cuffed Yakuza in the head, the cuff on the right is suddenly detached and bent out of shape.
Continuity mistake: The clock time on the top right of the laptop screen near the start changes from Sun 17:59 to Sun 16:00. (00:08:39)
Continuity mistake: After David has sent his daughter texts asking since when does she not text at school, it shows he's in a video conference with some other people split onto 3 screens on his computer. The image of his boss above and the image of the 3 people to the left of David's video never changes. However, upon cutting to closer or further angles of David's video, it frequently switches back and froth from a mirrored image or not. Despite there being no reason for it switching depending on the movie's camera. (00:15:40)
Continuity mistake: The main character is exercising in the gym and in the background is a man on the abs machine holding the handles above the grips. In the next shot he is holding the grips, and then next shot back to above the grips. (00:38:00)
Continuity mistake: The clothes Tyler and Kassi were wearing at Kassi's house were not the same when Kassi came to dinner that day at the Burnside's house. It seems unlikely that BOTH would change clothes before dinner. (00:31:49 - 00:32:40)
Suggested correction: Apparently they did. It was probably Tyler's idea, presenting Kassi in the best possible light to assuage suspicion and maintain his image as a good Christian Boy Scout.
Continuity mistake: When Stallone kills the bad guys with skull masks in the corridor of the bar, his motions pointing the pistol don't match the positions of the lemming-like goons he hits. For instance he has the gun all the way to his right for the first one he kills, but the guy is shown with a hole opening in his forehead while he's in the middle of the corridor. (00:29:00)
Continuity mistake: When Specs makes the bad joke about the "Winneba-ghost," Tucker goes from looking forward at Elise to looking sideways at Specs instantly between cuts. Then, in the very next shot, Specs goes from looking at Ted to looking at Tucker and Elise instantly between cuts.
Continuity mistake: Spencer makes his "Pie" gesture in different ways (fingers spread out, fingers adjoined) between the two wider shots and the narrow angle one. (00:09:15)
Continuity mistake: The glass near Jonathan's plate (in the upper left-hand corner of the screen) changes to the left of Mrs. Marsh's plate. (00:35:57)
Continuity mistake: Vera looks at her watch and sees there is only nine hours and 27 minutes left. She has two fingers placed against the top of the watch in the close-up shot, but when the camera cuts back to Vera, she only has one finger pressed against it. (01:19:50)
Continuity mistake: Jeffrey downs all his whiskey, but in the following shot his glass is still half empty. (01:35:50)
Continuity mistake: In the car at the start, when Hamilton says it's like the fourth blackout today, Michael corrects her and says it's the fifth. When he says this, he is leaning forwards some as he looks up out the windshield with his mouth partly open. It cuts to a different angle and suddenly he's leaned back in his seat fully and his mouth closed. (00:01:30)
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: 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: 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.
