Other mistake: When Helena Bonham Carter removes the necklace from its case, the clasp of the necklace is obviously closed (or at least it should be-otherwise it would slip inside the case itself from the raised mount that it is kept on in the case when the case is being carried) ; she is carrying the top of the necklace (where the clasp is) in her left hand while her right hand carries the bottom of the necklace. Had the clasp been open in the case, her arm and hand motion when she picks it up with her fingers would not have been so smooth. She goes over to Anne Hathaway with the clasp obviously opened (because we see her put the necklace around Hathaway's neck rather than over Hathaway's head) and then she closes it. When she tries to open it a few minutes later the security guard informs her that she cannot open it; that it can only be opened with a special security magnet - which he then proceeds to use to unlock the clasp. In other words, the necklace would have needed to be opened by the security guard to begin with before Helen Bonham Carter could put it around Anne Hathaway's neck. (01:01:05)
Other mistake: At the beginning of the movie, Kate is going through old tapes recorded by her dad on a TRV280 handicam. The second tape shows her as a baby in her dad's arms and it's dated Dec 25 2007. She starts a recording on a leftover blank tape and we see the date; Dec 24 2018. Her brother taunts her holding the camera out of her reach and tells her "You're 10 years old. Almost 11!", and she asks "So?" She should have said "You jerk, you don't even know my age?" She is 11 already. (00:01:00 - 00:04:15)
Other mistake: Just after signing the contract, you briefly see Stan in his hotel room. The smoke from his cigarette is moving downwards.
Other mistake: Vanellope steals a car from the Slaughter Race game and speeds off. Shank, the main character of the game, commandeers another car and chases Vanellope. When Shank's car is seen in Vanellope's rear-view mirror, the image is not reversed. Shank appears to be driving from the passenger seat.
Other mistake: Peik Lin is driving Rachel to the Young family residence. As they are driving, the navigation system starts prompting her to make a u-turn because there's nothing out there but jungle. Peik Lin brings the car to a stop, seemly indicating that they are lost and unsure where to go. The guards suddenly appear and then eventually give her the go ahead to go through a very visible gate. The gate is prominent. If the gate were that visible she and Rachel wouldn't have wondered if they were lost or in the wrong place.
Other mistake: Outside the prom when Hunter is trying to convince Lisa and Mitchel to not go in and stop their daughters from getting laid, they turn around when they hear the honk of a car behind them where two people are having sex as if they bumped the car horn. However this is impossible as as soon as they turn around, the two people are in the back seat right behind the driver's seat, nowhere near the steering wheel to honk it, even with a foot. (00:35:45)
Other mistake: Daphne's dad drops the Legitimate Tulip badge in front of her so she'll avoid getting hurt, but when we see him do that, he does it before the warning for the ball is heard and seemingly not looking at the danger (especially in the second shot, when he is peeking from the corner). So his action makes no sense. (00:16:55)
Other mistake: When Tony and Dr. Shirley are driving in a snow storm, in the view from the front of the car, the wipers seem to pass behind the snow on the windshield, and the blades appear longer than the area cleared. It's almost as if the snow was added on later in post-production. It's most noticeable if you look at the tips of the wipers as they approach the tip of the snow on the windshield. (01:51:35)
Other mistake: The protagonist finds out that his wife is cheating on him, and decides to try to dial the killer. We see his phone number, it's 328 241... Later on, after visiting his brother's parish, he tries to contact his 'frenemy' again but the number now is 386 909.etc. He can't have changed number in that short while (and the protagonist wouldn't know anyway). (01:03:10 - 01:10:55)
Other mistake: Willowdean is disqualified for not having her talent costume approved - but the girl who gets 2nd runner-up [Millie) is also wearing a different costume than the one she had approved, and she is not disqualified.
Other mistake: After the three kids took the car and caused a 19-car pile-up on the 141, Social Services got a court order removing them from the home and parents were not allowed to see them. Social/Child Welfare Services try to maintain or preserve the family unit and view removal from the home as a last resort or in cases of severe neglect or abuse that endangers the child. Social Services would not be likely to take such drastic measures for this incident. The driver may have been adjudicated a PINS.
