Revealing mistake: When the Sergeant has the shotguns in the backpack on his back, and you see a close up of his face, you can see that the shotguns do not have triggers. On plastic prop rifles, the trigger is usually molded into the trigger guard in the pulled back position, and you can see this on these prop shotguns.
Revealing mistake: In the scenes where Riley is using his computer to look up information on the "SearchInfo" site, the screenshot used is of Wikipedia. (You can even see the "About Wikipedia" link on the left).
Revealing mistake: When Laura falls in the bathtub, a stunt is doing the fall, because her hair colour and style changes.
Revealing mistake: When the police dog wants to attack Swagger and bites the cop instead, it's obvious the cop wears thick protection under his coat sleeve. (01:03:20)

Revealing mistake: When Kale and his father are hit by the red truck at the beginning of the movie, a rectangular hole can be seen in the trunk where the spare tire is, obviously not for the tyre itself or made by the crash. (00:04:25)
Revealing mistake: At 39:55, actress Jaime King gets out of the shower, and she has just reached for her robe, and then on the bottom right corner of your screen you can see a bit of the flesh-colored body suit she's wearing. Continue to 40:00 where you see it again. Continue to 40:05-40:09 where you can see it, without slowing or stopping frame. (00:39:55)
Revealing mistake: During the long tracking shot at Dunkirk, steadicam operator Peter Robertson had a little assistance in getting around. This took the form of a kind of golf cart (from the beginning to just after shooting the horses), and later a rickshaw (from little after the choir to just before the steps ascending the billets). If you look at the ground to the left just as the camera begins backing away from the carousel, you can see tracks in the sand made by the rickshaw. Keep watching the sand near the actors' feet to see more.
Revealing mistake: Meatwad and Shake get booted off the computer by Frylock so he can find instructions to the Insane-O-Flex. Watch the computer monitor. It rumbles, but the logo on it stays still.
Revealing mistake: An obvious double for Anne Archer the morning after her assault. The double's hair isn't shoulder long and is thicker than Archer's.
