They may be fun, sugar-coated fare, but they're not immune to errors, and we have the evidence!
From classic animated films like "Beauty and the Beast" to live-action flicks like "It's a Wonderful Life," here are 21 of the worst "oops" moments we could find in your favorite family movies.
Gallery | Worst Family Movie Mistakes
- 'National Treasure' (2004)
Benjamin Gates's (Nic Cage) younger self is played by a boy with brown eyes. Cage has blue eyes. Interesting casting choice.
- 'Toy Story 2' (1999)
In this scene from 'Toy Story 2,' Hamm shuts off the television with the remote. When we get a look at the TV, however, there's no reflection of him or Rex to be found.
- 'Monsters Inc.' (2001)
When George comes out of the door with the kid's sock stuck to him, the sock's toe points inward toward the middle of his back. When the CDA rushes in to remove it the sock toe faces outward.
- 'Aladdin' (1992)
While the palace guards are arresting Jafar, no one has noticed that the curtains have magically disappeared. It had to be Genie, right?
- 'Harry Potter and the Chamber of Secrets' (2002)
Presenting our first visible crew member of the list. Someone get that guy some wizards robes!
- 'Beauty and the Beast' (1991)
The case of the disappearing apron. In this scene from 'Beauty and the Beast,' Belle somehow makes a wardrobe change in the blink of an eye. First you see the apron, and then you don't.
- 'Jumanji' (1995)
In this "Jumanji" still, the license plate in the top photo clearly reads "G2298." After the cop car goes airborne, however, the plate changes to "CFJB95." Also, with a different bumper, it's clear they are two separate vehicles.
- 'The Wizard of Oz' (1939)
Anything can happen in the land of Oz. You even have the ability to cry straight from your eyebrows. Just ask the guard in the green get-up.
- 'Willy Wonka and the Chocolate Factory' (1971)
Everything is fine and dandy in this opening musical number from 'Willy Wonka.' That is until the Candy Man inadvertently smacks a young girl in the chin (for better visual evidence, check out the full clip here -- it happens at the 1:58 mark).
- 'Matilda' (1996)
Since Matlida has special powers, we should let this one slide. However, the giant cross missing on the chalkboard is pretty obvious. Another case of something being there one moment, then vanishing the next.
- 'High School Musical 2' (2007)
This scene still boggles the mind. One moment, Zeke is sitting on a stool big enough for his feet to dangle from it. A second later, it's become a mini-stool. Didn't anyone on the set notice? Zeke, speak up for yourself!
- 'Ghostbusters' (1984)
The newspaper photo of the Ghostbusters from the middle of the movie is the same shot we see at the end. So, these guys fight ghosts and travel through time? We smell a 'Ghostbusters 3' plot line!
- 'It's a Wonderful Life' (1947)
Even a film as beloved as this one is bound to have a few mistakes. In this particular scene, where George is about to jump off the bridge, the snow momentarily cuts out.
- 'Home Alone 2' (1992)
Man, we miss Kevin McCallister and his crazy antics. In this scene from 'Home Alone 2,' he's being chased by Marv and Harry through New York City. To evade them, Kevin buys a necklace, breaks it and throws the pearls on the ground. Problem is, the "Sticky Bandits" end up slipping on twice the amount Kevin had originally put there.
- 'Miracle on 34th Street' (1994)
The second Mara Wilson film on this list (seriously, whatever happened to her?) features bangs that grow by themselves in a matter of hours. We guess miracles really do happen.
- 'Honey, I Blew Up the Kid' (1992)
Directors don't always have a big special effects budget. Still, the filmmakers behind 'Honey, I Blew Up the Kid' could have just cut this scene out. That way, we wouldn't have gotten to see actress Keri Russell's stunt double, who looks nothing like her.
- 'The Karate Kid' (1984)
Similar to the mistake we saw in 'Matilda,' this scene from 'The Karate Kid' uses two different notes Mr. Miyagi left Daniel. One has an exclamation point, the other does not. So much for self-discipline.
- 'The Chronicles of Narnia: The Lion, the Witch and the Wardrobe' (2005)
We respect the fact that family movies shouldn't be gratuitous about violence. But in this scene from 'The Chronicles of Narnia,' they could have been a little more realistic about Peter getting stabbed in the arm. The sword is barely touching him.
- 'The Little Mermaid' (1989)
Our last animated mistake comes courtesy of 'The Little Mermaid.' When Ariel and Eric are sitting in the boat, Ariel's hair is down. In the next shot, we see a reflection of her shadow in the water, which clearly shows the mermaid's hair in a ponytail.
- 'Cheaper By the Dozen' (2003)
This 2003 comedy starring Steve Martin was a huge box office success, despite the scene above, where a boom microphone is clearly visible behind the comedian.
- 'Back to the Future' (1985)
Great Scott! The odometer in Doc Brown's DeLorean has different readings several times in this scene, as does the trip counter. Also, if you look closely at the needle, you can tell that it's a different display being used.
- 'Spy Kids' (2001)
More boom mics! In this scene from 'Spy Kids,' a giant microphone is clearly visible in the reflection of the car's window. Whoops.
