Continuity mistake: During one scene in Camryn's Halloween birthday party (where she is wearing a silver mask), it is actually Tia playing this role instead of Tamera.
Other mistake: In the beginning of the song about Augustus Gloop, computer generated Oompa Loompas can be seen running through the Chocolate Room, preparing to sing their song. In the DVD release, some Oompa Loompas can be seen running to places that no real person could possibly stand on. This mistake was later corrected in the Blu-Ray release.
Continuity mistake: Straight after the second task Hermione wraps her own white towel round Harry, but between shots it jumps back to her shoulders, then back to Harry's several times. (01:35:05)
Visible crew/equipment: When Mrs. MacReady meets the Pevensie children at the train station, the reflector screen is reflected in the lenses of her glasses, as she looks down when she speaks to them. It is also visible when the children first arrive at the house, when Mrs. MacReady says, "There shall be no disturbing of the professor." (00:07:30)
Character mistake: In the scene where Steve and Josie prepare to leave to fight the giant robot at the beginning of the movie, Steve tells Will "Oh, Will, a reminder: a lot of the kids at Sky High will only have one super hero parent, not two." When he says "one super hero parent", he holds up two fingers. When he says "not two", he holds up only one finger.
Visible crew/equipment: When Shane is talking to Mrs. Plummer before she leaves, throughout the scene the camera man is reflected in her window (he is in black, not to get confused with Shane's white shirt) and as the car drives away the camera is shown backing up in the black door.
Continuity mistake: Look at the dirt when Herbie backs away from the nose of the newer Beetle, between the races out in the desert. Although Herbie drove straight up to the newer Beetle, tire marks can be seen where the crew moved the car back and forth to get him lined up.
Continuity mistake: After Casey has turned down Harvard and is skating on the pond, she falls many times. When she falls for the fourth and final time, her hat falls off. In an overhead shot, the camera even shows it laying on the ground above her head. When she gets back up upon seeing Teddy with the zamboni, her hat has disappeared. (01:12:05)
Continuity mistake: After Evangeline has left with Aunt Adelaide, Nanny McPhee enters the children's room, and as she and Chrissie walk to the bed they pass Eric's, Lily's and Tora's beds, with the bare wood floor at the center - there is no rug. However, when Nanny McPhee leaves their room the long red and white rug is at the center of the floor, between all the beds. (00:51:55 - 00:52:55)
Continuity mistake: When the car blows up at a rest stop, when the children run to Ice Cube, the boy is on his left. However, when they turn around and sit, the boy is on his right.
Other mistake: It was established in the first Mask that the mask does not work in the daytime, but it works during the day in this movie.
Other mistake: It's been stated that Danny doesn't know how to read. This is evidenced by the fact that Walter has to read every card that Danny gets. When Danny first finds the game, he's able to read and even pronounce Zathura accurately even though he is illiterate.
Continuity mistake: In the fight between Barkis and Victor in the church, Victor slashes at Barkis with the fork and leaves 3 very noticable tears in Barkis' jacket. These tears aren't seen in any of the subsequent shots. (01:09:15)
Continuity mistake: In the scene where Chicken Little lends the alien baby, Kirby, his handkerchief, after Kirby blows his nose, it sticks to Chicken Little's hand. Chicken Little then wipes the hanky off his hand on to the grass. In the very next shot, the hanky has disappeared, and never shows up again.
Revealing mistake: When Tom joins Sarah and Eliot for the kneeboarding, after Sarah apologizes for Tom's interrogation Eliot says, "It's okay, my dad would've done the same thing." Two shots later, as Tom grunts in the water, this shot is flipped - the driver is now on the left and the kids switched sides.
Continuity mistake: Following Rodney's step from the escalator on the red pedestal he is being scooped into one half of a wire-frame globe/ball. Two halves now (the other one has Fender in it) form an intact globe. A safety bar with a 'wooden' middle bit (like those on rollercoasters) suddenly appears. After their journey, when the ball splits back into two halves, the safety bar, which previously had mysteriously appeared, now has disappeared.
Continuity mistake: In the opening shot at the breakfast table, there is a large cereal box and a carton of milk on the right side of the table, in front of two salt-n-pepper shakers. But during the scene it continues to swap to an angle behind the two shakers - but now the cereal box and milk carton have vanished, so as not to block the view for this angled shot. (00:12:30)
Factual error: In the sequence where the animals get on the first subway, it says they are on the 59th St subway. But, there is no 59th St subway in NY. The only subway station close to 59 is the 57th St subway.
Suggested correction: While the other correction lists a 59th street, that's in Brooklyn. There is one in Manhattan though, 59th - Columbus Circle, which is also the south-west corner of Central Park.
Suggested correction: There is definitely a 59th street subway station: https://en.wikipedia.org/wiki/59th_Street_ (BMT_Fourth_Avenue_Line).
Audio problem: In the scene where Phil starts to cry when he's kissing his wife, you can hear him say "I'm in way over my head" but his lips don't move at all. (00:34:20)
