Scooby-Doo (2002)

Revealing mistake: When Scooby, Shaggy, Mary Jane, and Daphne go crashing through the window while running from the two monsters, the falling glass and broken window frame pass right through the CGI Scooby. (00:42:30)

Revealing mistake: When Fred smashes his arm through the round window of the garage and grabs Shaggy, if you look you can see some kind of clear tape on his arm to protect him from the glass. This is quite noticeable in closeups. (00:47:10)

Revealing mistake: When the monster that got into Daphne is being destroyed by sunlight, everything else in the room seems to have frozen for a second. Carefully look at Daphne. (00:53:50)

Revealing mistake: When Daphne and the wrestler are fighting on the roof, Daphne slams the door into the wrestler and the wrestler's head smashes through the door window. The wrestler then grabs Daphne's arm, and smashes his arm sideways into the doorframe. If you look closely, you may have to watch a few times, you can clearly see the pre-cut line that makes the doorframe easier for him to smash. (01:09:40)

Revealing mistake: When the gang and Mary Jane are being chased down the corridor and jump out of the window, you can see that it isn't Daphne that hits the awning. It's a man in a dress.

Revealing mistake: When Shaggy, Scooby and Mary Jane have escaped the monsters using the quad bikes, they land in a small pit and Scooby starts barking at Mary Jane. When Shaggy says, "Scooby-Doo like what are you doin' man", Shaggy is talking to the floor - he's not looking anywhere near the CGI Scooby.

Revealing mistake: When the gang is chased out through the window, Scooby pushes them on a cart. During the shot, on the floor, you can see the tracks that the cart is travelling on.

Revealing mistake: As Pamela Anderson comes crashing through the gates at the factory, the floor camera is knocked slightly.

Revealing mistake: In the little clip at the end, Scooby Doo opens a jar of peppers and dumps them in his mouth. You can see that there should be more in the jar than the seven or so that fall into his mouth, but suddenly the jar is empty.

Revealing mistake: After the little Scooby-gang has crashed through a window after being chased by monsters they bounce upon an awning and you can see that the glass from the window is now paper.
