Factual error: Trevor - a Professor of Geology - boasts about having an article published in Scientific American, and that is not something any scientist would do. Scientific American is looked upon with slight disdain by the scientific community, considered to be a populist crowd pleaser. It is not even peer reviewed. Considering that he has just turned the geological and archaeological worlds on their heads he would have been better off publishing in Journal of Geological Research or Geology, both prestigious professional journals.
Plot hole: At the start of the movie, a great deal is made of the boom mic that enters the shot. This is ridiculous, because Bolt's view would not be restricted to what was onscreen, he'd have a perfect view of the person holding the boom mic (as evidenced by it not being stable). There's no possibility of him not seeing the person holding the mic either. As Bolt completely and utterly believes the world he lives in, and thinks the situations he finds himself in (saving Penny) are real, someone holding a boom mic would break the illusion for him. In all instances in the movie where an outside force (i.e. a dog handler) interacts with him, Bolt never gets to see the person handling him (handler approaches from behind), the boom mic operator however is literally right in front of him.
Suggested correction: He wasn't paying attention and considering that his focus was only on the "action", how the hell would he notice a boom mic when he's trying to protect Penny? His "reality" is never broken even AFTER he's in his trailer.
Revealing mistake: When John picks his wife up at the airport, it's raining. But look at the people around outside, they are in T-shirts, in the sun, and not getting wet. Obviously the rain is being sprayed on the car.
Continuity mistake: At Riley's Garage, when Troy and Chad are about to rummage through the junk looking for the radiator cap, Troy raises his arms and his boxers are light grey, but next shot when he lifts the truck's hood his boxers are black. It's also noteworthy to mention that during "Boys Are Back," young Troy is wearing patterned boxers, though all other clothing is identical. (00:53:45)
Continuity mistake: In the scene where Chief James Porter is watching his daughter dancing through the window, the curtains are all the way closed. When he gets a ladder to climb up, the curtains are a 1/4 of the way open.
Continuity mistake: In the scene where Hogsquel gives Jared "the sight", after he spits in his eyes Jared is holding the seeing stone, but in the next shot when he is wiping the spit from his eyes the stone is gone.
Visible crew/equipment: When Alexandra is being harassed by the hagglers, she gets into a man's truck after he tells her he knows where to take her. As the truck drives out of the shot the camera is reflected in the window.
Factual error: As a trash compactor Wall-E does not function logically. When he fills his chest compartment with garbage and runs his internal compactor, the cube that exits his body is the same volume as the trash he puts in, despite that trash having been compacted. He does not add extra trash to fill the empty space after running the compactor - there are three scenes that show him filling up only once with loose garbage and then ejecting a densely compacted cube. (00:02:30)
Suggested correction: You haven't noticed the exact shape of his body. The back sticks out a tad. Garbage fills the space and the back pushes in to compress it.
Continuity mistake: When Brown pours water on Shane to wake him up, the wet patch on his clothes changes appearance between shots.
Factual error: In the very first scene a giant squid swims past Fujimoto. It swims in the wrong direction however, with its tentacles in front. In reality squid swim backwards.
Continuity mistake: When Shifu performs the Wuxi finger hold on Po, in one shot, we see all of Po's fingers, except the one Shifu is holding, are closed to his palm. In the next shot, all his fingers are open. (00:22:05)
Suggested correction: If you slow down before the part where the camera pans onto Po when he's surprised, his fingers open.
Plot hole: The newspaper headline showing young Alex being rescued from a crate is dated April 8, 1972. In the next scene, we see young Alex dancing in the Central Park Zoo, and watching him are Marty, Melman and Gloria as baby animals. This makes no sense at all. In the first film, Marty celebrates his tenth birthday. Key word: tenth. It is also known that the scenes of the main characters as adults take place in the present i.e. Alex confessing to breaking Marty's iPod. Seeing how the animals age quicker than humans, Marty, let alone his three friends, would have to have been born in the mid-1990s and the flashback scenes could not have taken place in 1972.
Audio problem: The chairman talks to the mayor, and says that "no one supports you." When he says "supports", his lips look nothing like it.
Revealing mistake: When Budderball is rolling down the hill in a snowball, he hits a tree and falls out. You can tell it is just a stuffed animal since there is a stitch on the top of his head.
Continuity mistake: Right at the beginning, the kid's hand keeps swapping from being on the middle of the paper to on the upper part, between shots.
Continuity mistake: When Tinker Bell tries to fix the music box there is a leaf in the box, when she is done it's gone.
Continuity mistake: In scene two, when Rachel is getting ready in the bathroom with her friends, she is wearing her shoes. Chloe (the dog) is mad because she wants to be fed, and after she is given dog food, puts a clump into Rachel's shoes. She should have not had her shoes on in the bathroom in order for this to make sense.
Continuity mistake: In the part when Lina and Doon are looking at The Book of Ember, they open it to a few pages in. But in a later shot, it shows they are near the middle of the book.
Continuity mistake: When Maya gets in the car to go to the White House, she's in a blue outfit, but is in a brown skirt and pink jacket when she gets there. Despite the fact she could've changed in the jet, she wouldn't have known she was going to be on a private jet, and so would've been wearing what she intended to wear. (00:13:00)
Continuity mistake: When Skeeter arrives at his sister Wendy's house, he walks into the kitchen and meets Patrick and Bobbi. He says he has some presents for Bobbi, and Patrick turns around and leans his arm on the back of the chair. In the next few shots his arms keeps moving from resting on the back of the chair to down in his lap.
