Best family movie revealing mistakes of all time

Revealing mistake: As Kevin is flying off the front porch on the toboggan, you can see the small wheels mounted on the bottom of the sled to aid in its "jump". (00:25:30)

Revealing mistake: At the beginning of the scene near the end of the movie with Lucius Malfoy fuming at Dumbledore in his office, Malfoy's hair is fanned back behind his shoulders. The lighting in the room illuminates the back of his neck, where you can see his real, short brown hair. (02:22:05)

Revealing mistake: At the start, when Data is being pulled towards the chained orange drum, due to the angle of the close-up, we see that the soles of Data's Nikes are not actually touching the ground (since there is a rolling mechanism under his feet). Despite the fact that Data is quite inventive, we see in the next shot there's nothing attached to Data's Nikes. (00:03:55)

Super Grover

Revealing mistake: When Darth Vader and Ben are fighting, Darth's chestplate is on backwards and the belt "buckle" is as well. It appears that the entire shot was reversed. (01:26:20 - 01:27:15)

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.

Revealing mistake: In the final game against Iceland scene, there is a point where you can see that the people in the stands are actually cardboard cut-outs.

Revealing mistake: In the Forbidden Forest, HRH are introduced to Grawp. Just as the giant lifts Hermione off the ground, in the shot from behind her, Hermione's legs disappear below her calves; the digital lines are actually visible. Slow-mo is not necessary. (Only visible on fullscreen DVD.) (01:29:40)

Super Grover

Revealing mistake: When Matilda telepathically makes the TV explode, you can see what looks like parts of an explosive hidden behind the screen.

Revealing mistake: After visiting the merchant, Kristoff's guitar has four strings, but only three tuning pegs.

Revealing mistake: When Troy says "I'll sing with her," Ms. Darbus turns around "in response" to his voice before he even says anything.

Revealing mistake: When Tallulah and the girls are acting in the Fat Sam's Grandslam song look at Tallulah as they sing the 'Ra da da da da da' bit. She looks straight into the camera.

Revealing mistake: When Hallie trashes Annie's cabin and the huge water balloon is about to fall on Annie's head, the camera is at a downward view and Annie clearly steps into the trail of the balloon instead of jumping away. (00:18:05)

Revealing mistake: Just after Harry attacks Snape at the Shrieking Shack, he insists on knowing about Peter Pettigrew. In the next shot, as Lupin says, "He was at school with us. We thought he was our friend," there are wedges under the wheels of the piano, however, in the following shots they're gone. (01:34:10)

Super Grover

Revealing mistake: After Carmen rescues Juni, as they fly over the city she says, "Hang on butterfingers." In the following close-ups, where is the handcuff with the broken chain on Juni's wrist? He is not wearing it on either wrist in any of these close-ups. It's obviously back in the following shots. (00:41:45)

Super Grover

Revealing mistake: When the Wicked Witch scares the Munchkins in Munchkinland, where Dorothy lands, she disappears into a cloud of smoke she creates. But you can see her sneak down into a trap door below. [As a sidenote to this entry, Margaret Hamilton was hospitalized for severe burns after a take of this shot (not the final one used) when there was a glitch in the timing of the explosion.] (00:30:45)

Revealing mistake: In the part in the motel where THING is doing morse code on the table to Gomez you can see the cut-out in the table where the guy's hand is sticking through the table.

Revealing mistake: Daniel Radcliffe, the boy who plays Harry Potter, has naturally BLUE eyes. In some shots Chris Columbus, the director, changed Daniel's eye color. But Chris C. didn't want to use that the whole time. It's NOT a lighting problem.

Revealing mistake: When Vic Frohmeyer excitedly tells the kids that Mr. Krank is putting up his frosty, the kids turn their attention away from their video game and get up to leave, but the video game continues to be played, indicating the video on the screen is a recording. (00:59:20)

Revealing mistake: Aboard the Hogwarts Express, when Harry stands beside the open window and sends Hedwig off with the letter for Sirius, surely his hair and clothes would be wildly moving about, because of the strong wind from the fast moving train.

Revealing mistake: Underdog's first costume is supposed to be a felted down (the more accurate term would be fulled) wool sweater. When wool is felted the stitches lose clear definition and usually achieve a "felted" look. It is clear that the sweater in the movie has just been switched for another smaller sweater as the stitches are still sharply defined after it has been pulled from the dryer. This is especially clear around the U. No attempt to make the smaller sweater look "felted" was made. This refers to the original costume with the solid white U, not the second costume with the yellow outlined U.
