Continuity mistake: Velma reluctantly agrees to Daphne's idea to check out of the mysterious locker. She says "We'll come up with something." Right part of the frame, and in the background there's an extra (black kid with a plaid white shirt) that is simultaneously also eating at the table in the reverse shot. (00:31:15)
Continuity mistake: When Shawn first holds up the jerky to distract the guard dog, he's holding the torch in his right hand and the bag of jerky in his left. We cut to a wider shot and the items have instantly switched hands. (00:26:50)
Continuity mistake: During the first appearance of the true Candyman, there is sunlight where he is standing. The sunlight disappears in the close-up.
Continuity mistake: When Dani is looking at Simon and Connie complaining to Ingemar after the female elder jumps off the cliff and they turn back to face towards it, Christian says "Oh my God" realising the male elder is about to jump off.

Continuity mistake: In the classroom when Peter is being possessed, he slams his face down into his desk twice, splattering blood onto it. After he falls back screaming, the camera changes angles and now his desk is clear of blood. (01:38:25)
Continuity mistake: At the beginning of the movie when Cooper and the kids arrive to the lake after they took the control of the drone, Murph steps out of the truck and leaves the door open, but in the next shot the door is closed and it's sure that in the entire scene there's no sound of a car door getting closed.
Continuity mistake: Velma adds books to the pile in front of her when she takes the telephone order. Looking down the pile, you don't see any trace of the random loose papers that appear when she hauls the whole lot to the desk with the TV on. (00:06:25)
Continuity mistake: When Don Knotts is in the old Simmons mansion, he falls down a chute of some kind. If you watch closely you will see the stunt person looks nothing like Don Knotts. It is a younger man with very straight hair.

Character mistake: When Mr. Brooks and Marshall hack into the police database and are looking at detective Tracy Atwood's financial records there is a screenshot of the computer screen showing some very terrible spelling.
Continuity mistake: When Peacemaker kills Rick Flag by stabbing him in the heart, the depth of the object changes between the close-up shot of Peacemaker's hand and the next shot, where we can see the part sticking out of Flag's chest has increased. This is before Peacemaker hits the object deeper. (01:31:05)
Continuity mistake: When Sook-Hee is standing outside in the rain before leaving, she is shown holding an umbrella whilst it rains. She walks over to say goodbye, whilst still holding onto it. A second later, she leans in to kiss a baby on the head, and the umbrella is no longer there. It is shown later that she placed the umbrella on the ground, but she was not shown doing this earlier in the scene. It just disappears in between shots. (00:02:20)
Visible crew/equipment: When the Nihilists are ordering food at the restaurant, you can see the reflection of the camera and cameraman in the window behind them. Watch as the scene pans around and you can see the camera and the cameraman move as well. Could the person behind the camera be Roger Deakins? (01:34:20)
Continuity mistake: When the girls bring a birthday cake into Judy's room at the first time, her bed sheet is patterned with what looks like flowers but when Judy is fast asleep the next time, the sheets are plain white. (00:52:30 - 01:15:30)
Revealing mistake: Just after the scene where Mark is killed, there's a shot of Jason's feet as he opens a screen door and walks across a dusty hardwood floor. As the dolly pulls backward across the floor, you can see the camera's roller marks in the dust. (00:59:10)

Continuity mistake: At the beginning of the scene inside the Dennis Nylon mansion, Emily is wearing her bag on the left shoulder. She sneaks her way inside the "employees only" area, loses her cover (the guy bringing clothes upstairs), still with the bag looking the same, but the moment she enters Emily's office in a rush, she is wearing her bag across the chest, right shoulder strap, bag on the left side. (00:34:00)
