Other mistake: In the scene where Tom Hanks and his son are riding in the car and Hanks is telling about the aunt in Perdition, a shadow is casted onto the hood of the car. However, the reflection of the clouds in the windshield never get blocked out.
Other mistake: It's raining when Nameless and Sky are fighting (rain is dripping off their swords and is on Nameless' face when going towards Sky in slo-mo), but their entire bodies never get wet.
Other mistake: When Austin, MiniMe and Foxxy are in Nigel's Mini, MiniMe is communicating to them with written notes. When he writes the first note to Austin, Austin reads it with the written words facing the camera. He is reading the back of the page where no words exist. Also, the words are upside down when facing the camera. In slo-mo, we can see the hand-off of the paper from Mini Me to Austin and how the front, top written on side of the paper ends up facing the camera and upside down. There is no way that Austin can read what is on the page. The paper is not thin enough to be read through as one other person has claimed. Foxy receives a note from Mini Me and we cannot read through the paper that is handed her. (01:08:30)
Other mistake: After Jason rams the man through the railing at the top of the stairs, he puts in a new clip. As he falls through the air, he shoots the other guard once. Then, he puts in a new clip when he rises after the fall. After one shot?
Other mistake: When the gang is in the mystery machine and Scrappy pees on Daphne and they kick Scrappy out of the car, from a distance the driver isn't Fred - it is someone with dark hair, not blonde.
Other mistake: When Carl and David go down in the submarine, they come across the sunken plane that they crashed in. As they approach the plane, it shows that the it is clearly on the right side of the sub as they go from the tail to the prop. When it cuts back to them in the sub, they are looking to the left. A cut back to the plane still shows that it could only be on the right. Carl then looks out the left port hole of the sub and it clearly shows them going by the plane from prop to tail.
Other mistake: When Gary and Gerti fall in the camel poop, there a few things wrong with that: 1) camels poop in "pellets", not like what you see in the movie; and 2) Gary and Gerti are both in the centre of the pile when they should be at the end of it. They are both in the same spot (it has nothing to do with leg length).
Other mistake: Every lake is frozen over enough you can walk on it except the lake where he falls. And he would have died of hyperthermia in 10 minutes or less, being wet.
