Other mistake: Whenever Verne is inside his shell, he has a tail (and references to it "tingling" are made throughout the movie), however, when he is out of his shell he has human-style buttocks and no tail.
Other mistake: When Bogomil gets shot two bullets are fired, one by the drive-by shooter and one by Karla, yet there are three distinct bullet holes and a forth large hole in the rear windshield of Bogomil's car. Two holes are completely unaccounted for. (None of the windshield holes are tree reflections.)
Other mistake: When the ride finishes, there is no sign of a safety bar in Gru's cart.
Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.
Other mistake: While Nisi and Mickey are in the kitchen, when Isaac and Manley walk in, on the counter is a box of instant grits with tape covering its brand name (Quaker) and a bit of tape covering the face of the company logo. Then when Mr. Blakemore takes out the ice cream there's tape covering its brand name as well.
Other mistake: During the one game playoff against the Yankees, the runner Taylor picks off at first base has the same number as the batter who had just struck out. Also, the number they both wear has been long since retired by the Yankees and therefore no player could ever wear it again. Again, in the first game against the Yankees, the first base coach also has the same number, making it three Yankee players with the number 37.
Other mistake: After the concert, when Dewey is telling Gordon how awesome the lights were, Eleni calls him Jack. The actor that plays Dewey is Jack Black. (This mistake is mentioned in the Kids Kommentary [sic].) (01:35:40)
Other mistake: When Martin Lawrence falls over the railing in attempt to get the mysterious necklace, the camera goes to another shot that pulls away from the moat. You can see the logo on the back of Lawerence's cover-alls swimming away at the corner of the screen, when he's supposed to be under water. (00:06:15)
Other mistake: Grand-Santa has made 70 missions, and Santa (Malcolm) has just completed his 70th mission, totaling 140 years. Yet Grand-Santa is only 136 years old.
Suggested correction: Grandsanta's portrait is shown in the halls of the North Pole with the dates 1902-1941 (with Malcom having done 71 missions from 1941). Therefore he did 39 missions. That makes for a total of 109 years, meaning he was 27 when he took over from his own father.
Other mistake: When Mike goes to Marcus's house to apologize, as Marcus lets Mike in and they walk through the house you can see the corner of a very nice built-in pool through the glass doors, even though a large part of the beginning and the end of the movie take place in Marcus's '$3900' portable pool and its subsequent replacement. (01:34:20)
Other mistake: Before the nationals, when Beca is getting dressed, we see in the mirror that Kimmy-jin is playing KINECT Sports, but when it pans to her, she is playing with a controller.
Other mistake: When the general passes the clipboard to the President to sign the nuclear release, the clipboard is actually upside-down. (00:55:55)
Other mistake: After Guy gets hurt in the warriors/ducks game, the scoreboard is shown. It says that there is 15 seconds left in the third period, when it is really the second period.
Other mistake: When Greg is looking at the video of Rowley sitting on the foil ball, he notices it has only 4 views on YouTube. However, if you look closely, it has 24,963 comments - impossible if it's only been viewed 4 times.
Suggested correction: YouTube is broken. This kind of thing actually does happen in real life quite frequently. In fact, a video I was just watching had that problem.
Other mistake: When Ringo and the young boy with the tire walk along the path together and the boy asks Ringo, "Why aren't you at work?," you can see Ringo mouthing the line along with him.
Other mistake: When Twoie first appears he is naked because he was just made. Yet when he walks toward the mirror, you can see at the bottom a strip of blue jeans.
Other mistake: When Kevin and Perry go home to find the postman at the front door, the postman asks Kevin to sign for a letter (his father's). If you look closely at the address on the postman's sheet it does not match the address on the letter. You need to be quick and look closely.
Other mistake: About 3/4 of the way through the film a boat arrives at the left quay of the Seine. Looking west down the river with Notre Dame on the right of the scene you can see a tour bus cross the bridge.
Other mistake: In the beginning of the movie when Kimberly is shackled to the floor you can see that the padlock isn't locked. She could just take it off and be free.
Other mistake: Near the end of the film there is a stand-off, if you look in the sky an aeroplane flies by.
