Revealing mistake: In one scene, when Jack is in the dungeon talking to the fairy, you can clearly see that the "fairy" is nothing more than a light on a thin piece of wire. The wire can be seen quite clearly for two shots.
Revealing mistake: When Gary and Wyatt come home and see Chet turned into a pile of poo, Chet shoots his tongue from his mouth and catches a fly. Look closely, the tongue flies completely out of his mouth and is attached to a metal spring. (01:24:55)
Revealing mistake: When Jesse is cleaning out his room, he puts a tape into his tape player, and presses a button down on the top of it. But halfway though the scene of him packing his things away, you can clearly see the button is no longer pressed down, yet the tape still plays. (00:18:10 - 00:19:00)
Revealing mistake: When Lowry first arrives at Buttle's flat to return the cheque, he hears a cough and turns to see a man smoking a cigarette, half hidden by a column. When he blows a cloud of smoke it is easy to see that it comes from a tube next to his mouth. He isn't even exhaling at the time.
Revealing mistake: When Stiles enters the locker room, a guy walks out the shower and you can see his black underwear. (00:05:25)

Revealing mistake: When Philippe the Mouse is caught by the Bishop's guards after he has escaped from prison, Navarre shoots an arrow into one of the guard's arms to stop him cutting Philippe's throat. If you look at the spot on the guard's upper arm where the arrow will hit just as Philippe says 'May God have mercy on my soul', you will see that there is already a hole there - even before the arrow hits him.
Revealing mistake: When Tenderheart Bear confronts Nicholas in the Cave, the light of fire Nicholas has lit casts a shadow of Tenderheart Bear on the wall of the cave. However, when Tenderheart Bear moves his arms, the shadow stays the same.
