Other mistake: It's been mentioned that Sid sets his clock for 8:25 and it goes off at 7:00. Here's some more errors for Sid's crazy clock physics. When Woody is saying "Psst" to Buzz from inside the blue plastic basket, the clock on the wall says 6:25, yet the alarm clock next to Buzz says 6:55. It goes off 5 minutes later and after Sid takes Buzz out of the room, the clock on the wall has changed to 3:10. When Woody is talking to Sid's toys a minute later, the clock now reads 10:00. The maximum amount of time that passed between the already wrong 3:10 and the 10:00 is 5 minutes. You can tell because Sid wanted to launch Buzz strapped to the rocket ASAP and Woody wanted to rescue Buzz from his current strapped-to-a-rocket state very fast.
Continuity mistake: After Gerry gets smacked in the face by the 'broken' suspender clasp, we see the silver clasp land under the dresser. Yet, when he's moaning and lifting his leg to get onto the bed, we can actually see the clasp still intact on the front suspender that came loose, which is dangling right behind him (just look between his legs). Of course, in the next shot, that clasp is gone. Since the silver clasp is one of the plot points, this is bizarre to say the least.
Continuity mistake: When John and Catherine are in the hangar at the runway, the Cessna's tail number is N3035C. When the plane is shown in the air, the number is N3973F. When they land, the tail number has changed back to N3035C.
Continuity mistake: In the bedroom scene the girl is holding a clear cup full of beer. The camera goes off her and when it comes back she is holding a blue cup. The camera goes back off her then on her and the cup is clear again.
Continuity mistake: When Sam is in his bedroom, after he finds the Cube sliver it falls and dramatically burns a hole through the floor into the kitchen. But Sam's bedroom is over the living room (there is nothing on the ground floor below Sam's elevated bathroom, and in the first movie Jazz hides in this open space), and the kitchen is actually located between the den and dining room, at the other end of the house. If they were to follow the actual floor plan of the house, the Cube sliver would have landed in the area of the piano in the living room, but where would the fun have been in that?
Continuity mistake: When Honey meets Hiro, she has earbuds in her ears playing music. She starts talking to Hiro, pulls them out of her ears, and they dangle out of her shirt. The dangling earbuds disappear in the close up shot of her and Hiro.
Plot hole: Even if boys of that age had the technical know-how to quickly repair Jeeps over 20 years old (seriously?), any gasoline in the tank would have long become unusable, the tires and lines would have rotted away, and the electrics would all be dead. Now if it was in the desert or a dry garage, it may have survived, but it's on a tropical island, in a shed that has all sorts of holes in the roof, leaving it exposed to every kind of weather the island could throw at it. In addition, the kids start the jeep with the small battery of an ATV, which cannot produce enough power to crank a Jeep engine.
Continuity mistake: When the Bellas just got told that they are not allowed to compete any more they walk outside and Beca gets a call. When the camera is zoomed in on her you see her calling and moving a lot. When the camera is focusing on the other Bellas she is standing completely still in the background. When the camera is back on Beca she is moving again.
New this month Plot hole: There's no good reason for Hinx to attack Bond on the train. Blofield was expecting him to turn up at the crater, that's why he sent the car to pick them up.
