Other mistake: When Mr. Peabody is fencing with Robespierre in the sewer, the sword goes flying up and causes the manhole cover to go flying up too. But then the manhole cover falls through the opening to land on Robespierre. There's no way a round manhole cover can fall through its own opening.
Other mistake: In the flashback of Bruce Wayne getting killed, his mother is cradling his body and weeping. She has his blood all over her hand from touching his wound. She rakes her fingers across his shoulder and down his chest with her bloody fingers, leaving no trail of blood, but when she places that same bloody hand on her face it leaves blood all over her face and mouth. (00:35:05)
Other mistake: In the crowd near the end, if you look very closely you can see unit 2013 twice.
Other mistake: When Nutcracker and Clara meet Marzipan the horse, Clara strokes her mane but if you look very carefully, you'll see that she's not petting her at all. She's actually just petting her in mid air without touching her at all.
Other mistake: In the opening titles, Irven Spence's first name is incorrectly credited as Irvin.
Other mistake: When Schadenfreude is playing the piano the first time he's on screen, he starts off by playing a slow, dark piece. Right before the piece turns to a more jazzy, upbeat number, he plays three final chords: The first is higher then the others, the second is lower, and the third is somewhere in the middle. But, if you watch his hands, the first two chords were mixed up: the first chord is played with his left hand on the lower half of the piano, and the second is played with his right hand, visibly on the higher keys. This doesn't match the audio, as the chord was supposed to be lower then the first, not higher.
Other mistake: When Lulu is looking at herself in a three sided mirror as a monkey, the reflections do not match up with her position of her hands. Most noticeably with the reflection on the right side. (00:05:40)
Other mistake: Before the Chipmunks and Chipettes begin their hot air balloon race, Klaus goes through the rules explaining that each team will be given the opposing team's doll when they reach various destinations across the globe. He then walks over to the Chipettes and hands Jeannette a trunk full of Chipmunk dolls - but they're not supposed to receive any Chipmunk dolls until the race is in progress. (00:14:35)
Other mistake: When Ariel hugs the adult Flounder, his eyebrows suddenly turn blue, then change back.
Other mistake: The Spanish version has all the titles and signs changed to Spanish text as we can see when Carl opens the photo album. However, a side angle shows the letters 'O' and 'D' revealing it's the original English text, "Things To do."
Other mistake: When Eddie Valiant gets thrown out of the Ink and Paint Club, he is already starting to go through the air as the gorilla moves his hands to throw him. (00:21:20)
Other mistake: When dragon Belle Bottom holds him up to her face and says "and now you're gonna pay.", there's no reflection of the terrified Gru in her eyes.
Other mistake: After the flood, Ponyo uses her magic to enlarge the ship along with all its accessories. At the end of the journey, Ponyo loses her magical powers and the ship shrinks back along with all the ship's accessories. A captain's hat is among the shrunk accessories, although Sosuke used it from the beginning of the film and it was always adult human size.
Other mistake: To get revenge against the reds for chopping off his hat, Benny goes inside the house to use the computer to change the woman's lawn mower order. Benny never hits the 'ENTER' key to complete things. Things are completed when he steps on the 'SPACEBAR'. Same thing happens later when Benny is ordering a female flamingo.
Other mistake: As the movie opens, Yogi is using a telescope to watch a family at a picnic table. The reflection in the lens should be in reverse but it is not. It shows the same view.
Other mistake: To save Sunshine from the general, Dex pulls on a rug to make sure the general falls backwards. However, Sunshine was also sitting on a chair on the same rug, but both her and the chair are unaffected by the rug being pulled. (01:14:05)
Other mistake: When EB is playing Rock Band, the TV shows the drum playing rapidly, but EB is playing the same beat he was before the solo.
Other mistake: At the end of the film, as Kenai walks up to Koda after he's been transformed back into a bear, Koda leaps on him in joy. If you look closely at Kenai's hind legs, there are a few frames of animation missing. His legs go from a standing to a sitting position instantly. It's barely noticeable (no pun intended).
Other mistake: During Lady's first night home, there's a shot of the family's clock: the number seven is painted as a six.
Other mistake: When the bus starts to leave the Hoover dam (as seen through Dallas' binoculars), the driver is missing. The steering wheel is shown with no-one behind it.
