Other mistake: When Rex shakes the table causing the baby monitor to fall, the batteries fall out and we see the open battery compartment with markings for positive (+) and negative (-), and space for two AA batteries. Woody jumps off the bed and places the two batteries inside the compartment, but before he closes the compartment note the position of the battery closest to the top of the monitor. The positive side is actually where the negative side should be so the monitor should not work, but the monitor turns on just in time to hear the soldier's warning. (00:13:15)
Other mistake: In the scene where Robin Williams tells Sarah that she needs a 12 to win, she rolls a 3. The next time she rolls, Robin tells her she needs a 7 to win.
Other mistake: George and Nina are sitting in the kitchen when the ceiling leaks from the rain and George makes a comment about the roof leaking. The only problem is it is a two-story house, so the water must be coming from the floor above, not the roof.
Other mistake: The fax machine Hoggett receives as a gift is different from the one he uses to send his application for the show.
Other mistake: When Ivan Ooze gives out those slimes to the kids, that boy is at the very back of that big crowd. As Ivan Ooze starts giving them out, it switches to the boy and he already has some slime, but it would have taken a few minutes for him to get one. (00:42:00)
Other mistake: Isn't it weird how in the final scene with the 2 pirate ships, both of these ships are continuously blasting their cannons at each other, yet the sides of the ship show little to no damage throughout the entire battle? You would think that the parts of the ship that are in the direct line of fire would get hit.
Other mistake: Just after Grandma Willow says "There's still some snap in these old vines," John Smith puts on his bag, but he just presses it to him instead of putting it over his head.
Other mistake: It's pretty bright in the cemetery considering that there are barely any lights.
Other mistake: As the priest walks out of the haunted mansion with his head twisted, you can see the head and body don't step in time together.
Other mistake: When Wallace sees the meat mincer, he says 'Now that's clever', but on the English DVD, the subtitles say 'Now the fat's cooked'.
Other mistake: After Marie and Fritz take off to the Christmas tree in the first scene where they talk to their parents, Fritz is shown pulling toy soldiers off the tree to play with. In the first shot of the tree, Fritz stands back up from the toys he has already taken down and reaches for another one. There is nothing in his hands. The spot he reaches for has nothing in it, but as soon as his hands reach that part, a toy soldier suddenly appears in the spot he touches, without the camera cutting. And then in the next shot he bends down and puts his hands on his toys as if he is placing the toy soldier with the rest, but there is again nothing in his hands.
