Factual error: During CONTROL's paintball training session, a barrel view of a bullet exiting the gun is shown as it travels to its target. However, the entire bullet is shown, casing and all, instead of just the bullet. (00:09:10)
Factual error: Basic physics - Hancock throws Michel from a dead stop to above cloud level in about eleven seconds. The clouds are bog standard cumulus which form at around 7,000 metres in temperate zones. This means that Michel accelerates to about 700 metres per second instantly, from a dead stop. Obviously he cannot accelerate during his ascent, so his starting speed has to be at least that. (In fact he would have to start his ascent much, much faster than 700 metres per second as he would be constantly decelerating due to gravity and air resistance, but it will do as a start point.) Michel accelerates from 0 to 2,520 kilometres per hour - twice the speed of sound - in zero seconds. He would be accelerating at around 5000 Gs, turning him into a very long streak of fine, pink mist.
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: During the scenes at her Mother's house, Kate's hair goes from blonde to REALLY blonde.
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)
Audio problem: When Britney Spears gets pushed into the Pit of Death, you hear her talk and scream but her lips are not moving.
Factual error: All the Cisco VoIP phones seen in the film have the booting Cisco logo on them and would not work due to no connection.
Continuity mistake: When Brennan rubs his nuts on Dale's drums, Dale comes in and starts fighting with him. Brennan doesn't have a chance to put "them" away but in the next shot his zipper is up.
Continuity mistake: During the police chase, the hub caps on Saul's police car keep appearing and disappearing throughout the whole chase.
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.
Factual error: In the scene where the camera shows Times Square, visible on the right of the screen in the front of the shot is a poster for the Broadway show "The Lion King". The Lion King just celebrated 10 years on Broadway and was not playing in 1994.
Factual error: In the title sequence, Poppy rides her bike down Kingsway, along the Strand, and south over Blackfriars Bridge. The next shot of her shows a street with an EC1 postcode (north of the river) and the following shot an SE1 postcode (south of the river again).
Revealing mistake: When Shelly and the girls (the playboy mansion girls) are getting their hair done for her birthday, the stylist is curling Shelly's hair but you see the iron doesn't touch her hair at all. (00:03:50)
Continuity mistake: In a scene early on where Mike is behind the video shop counter and Jerry is in front of it, the positions of the videos on the shelves behind Jerry alter from shot to shot.
Continuity mistake: When the guy walks in on Peter naked in bed, the sheet protecting Peter's modesty is covering him in one frame, and the next moment it has vanished completely.
Revealing mistake: In the scene where Big and Carrie meet in their cars after Big fled the wedding you can see down the street in the distance a huge amount of SATC fans have gathered to watch the filming. (00:52:35)
Visible crew/equipment: When Donna is telling Tanya about Sophie's dad arriving, stage lights can be seen in Donna's glass.
Factual error: After the boat has blown up and sunk, Ben swims over to it and checks it out, very little to anything is even a little charred, with that big of an explosion everything would be burnt, and black.
Visible crew/equipment: When Alison and Sidney are walking together on the street after a party, they cross the water and the shadow of the cameraman and the camera itself can be seen on the wall behind them and then again on Alison's face.
