Other mistake: After the magnet grabs Slink during the incinerator scene, all the toys grab metal objects to avoid getting torn up. Afterward, they all let go of their metal objects to drop down. However, Slink also drops down despite not holding on to anything because he is made of metal.
Suggested correction: Or, the other toys helped him down.
Other mistake: Before the battle, the leader of the waterbenders says that he will have everyone extinguish as many sources of fire as possible. When the firebenders come up from the ground at the start of the battle, all of the torches lighting the city are lit.
Other mistake: Towards the end when we see one of the $100 bill plates up close, the plate is not of any money ever put into production in the US. While I know most movies do not try and use actual money, there are things that don't match how real money is made: serial numbers are not on the plates, circle around Ben's head doesn't go to the border, "The United States of America" is missing above the "100" on the left, just to name a few.
Other mistake: When the ride finishes, there is no sign of a safety bar in Gru's cart.
Other mistake: In the scene where Jensen is attempting to decrypt the password on the hard drive with the algorithm, he uses the command "traceroute d-hea" which is commonly used to test network connectivity, not decrypt passwords.Then follows it with the command "dir" to reveal HTML code instead of directory structures.
Other mistake: When Tamina pretends to have fainted and Dastan runs over to her rescue, Dastan wearing some kind of Adidas/Nike/other modern sport shoes, only the shoe sole is visible but you can see it as he runs and kneels just before he gets whacked on the head. (00:36:45)
Other mistake: When Sly Stallone and Jason Statham decide to turn the plane around and attack the dock, they approach it from behind flying above land. But when Statham is firing the guns, one of the shots from his perspective shows it approaching from the water.
Other mistake: As the movie opens, Yogi is using a telescope to watch a family at a picnic table. The reflection in the lens should be in reverse but it is not. It shows the same view.
Other mistake: Although we could see that the soft porn by April, June and Machete was filmed with a static camera on a tripod with no one operating it, when Michael looks at the film it involved zooming, paning and tilting. On top of that, music is added to the film.
Other mistake: The lodge the guys are staying in is called The Silver Peaks Lodge. However, in the scene where Nick is confirming his reservation, the sign behind the clerk with the goatee reads The Silver Peak Lodge [singular].
Other mistake: When Sam Flynn first enters the arcade, he goes to a breaker box on the wall. When he opens it, the breakers are already in the "ON" position, closest to the center. He actually turns them to the "OFF" position.
Other mistake: When Edwin paralyses Isabelle with poison she almost immediately drops down and loses the ability to speak. When he tries to poison Royce and instead gets stabbed in the jaw with his own poisoned blade, Edwin gets paralysed and can't move, but still begs for mercy by saying "please don't kill me" when Royce drags him. (01:28:48)
Other mistake: Eustace's diary seems to be perfectly fine as he was making entries on board the ship despite it being fully exposed to the sea water.
Other mistake: Blake jumped through the window, shattering the glass and propelling many fragments through the air and towards/onto Edgar and Zoe, but no-one got cut. (00:34:10)
Other mistake: Harry pulls a knife out of Dobby's chest, but before that, we can see there's no knife.
Suggested correction: Yes there is, Dobby is holding on to it as he falls into Harry's hands. Its not totally obvious, but the CGI people definitely put it in.
