Revealing mistake: When Woody falls out of the closet wrapped in the string lights he hears Buzz's voice, and in the next shot as Woody sneaks up to Hannah's room we see Sid's open door and doorway, which looks perfectly normal. However, after Woody rescues Buzz from Hannah's tea party they both stop in the hallway, and there's another shot of Sid's open door and doorway, only this time it's not normal to say the least. Five of the six hasps, bolts, and locks that should be (and normally are) screwed into and attached to the inside of Sid's door (one hasp mechanism, third one down from the top, is attached to the door's frame) are now actually kind of floating there in mid-air right beside the doorway, as if there's an invisible door there. Weird that Pixar artists deliberately did this, but it's bizarrely funny to see.
Continuity mistake: Carl's cop car has the licence plate "G2298" which is printed thinly on the licence plate. Then, when the vine wraps around his car, and bends it in two, the licence plate is now "CFJB95", printed very boldly on the plate. The words "POLICE 004" also differ, as does the bumper and the lights. Totally new car, methinks... (01:14:55)
Revealing mistake: When the computer is being hacked and the password and/or code for the database is shown on the screen, most of the display is for an Autodesk printer driver. (01:39:00)
Continuity mistake: The girls are round Sam's Grandma's house drinking lemonade. Then when Grandma runs over to take their cups away, a cushion appears on Teeny's lap between shots. (01:11:55)
Continuity mistake: Mr. Svenning's junior college class ring mysteriously jumps from his left hand to his right hand just in time to get stink-palmed by Brodie.
Continuity mistake: Tai and Cher are hugging when they are watching Travis' skateboarding competition. Cher starts out on the left and Tai on the right. They hug in that position and then mysteriously end their hug on opposite sides.
Continuity mistake: When Lewis is on the phone with Congressman Jarrett, the phone Lewis is holding jumps back and forth from his left hand in the wide shots to his right hand in the close-ups. (01:27:15)
Continuity mistake: When Wallace is put into his overalls he's still wearing his green pullover. A moment later he suddenly doesn't wear it anymore but a complete white shirt. He couldn't have just taken off the pullover as the shirt under it is actually fake (The collar is actually part of the pullover and the arms are just stuck on).
Continuity mistake: When James and Kat first enter Whipstaff Manor, they drop their stuff on the floor. The large suitcase falls over on its side, but it cuts to the overhead wide shot and the suitcase is standing upright (the ghosts didn't do it). (00:19:45)
Continuity mistake: Kate is speaking to Charlie on the phone when he says he's met a woman. The length of the wire changes from short to very long instantly.
Visible crew/equipment: Whilst the group of Southeast Asian men are walking through the hair salon, there is a shot that starts with a male hairdresser wafting a blanket, that pans over to the group of men and then the camera rotates around the man holding a little girl. Immediately after the camera passes the man and girl, the camera very briefly holds on another man waving to an employee. Just as this happens, the reflection of the cameraman can be seen in the mirror to the left of the shot. (00:31:30)
Continuity mistake: When Lucy is in the Callaghan's house at Christmas at the very end of the scene it shows her stocking and her name on it is in white letters. However, in the scene where Mary comes in and tells the family that Lucy is pregnant, the camera pans to Jack who is standing right beside Lucy's stocking, only this time her name is in black letters.
Continuity mistake: Near the start as John and Charlie are walking along the street, the street is in the shadows completely. When the shot changes, half the street is now in sunlight. (00:11:00)
Visible crew/equipment: When Billy shows that he stole the shirt from Frank and lifts it up, you can see the microphone wire on the side of his stomach.
Visible crew/equipment: When the Jeep is flipping, in one shot, the door flies open and reveals that Ace is wearing jeans. Ace doesn't wear jeans throughout the whole movie showing that this is a stunt double. When the car falls in the parking spot, Greenwall seen through the door is very obviously a dummy.
Continuity mistake: When the boys are sneaking in to take the pictures of Payne, the first time you see him in bed the clock says it's 4-something. When they come back and get the boy in the dress in the bed, the clock says 12-something.
Continuity mistake: In the airplane scene, when Tommy reaches for the life vest in the overhead bin, he uses his left hand. But it's in his right hand when he removes it.
