Continuity mistake: Right after Bennett takes off in the plane, Claire throws a gun to Alice. Between the slow-motion shots, the gun switches position in mid-air before Alice catches it. In the shot of Claire throwing it, the barrel is facing to the right, meaning that it should be facing to the left in the shot of Alice catching it. But it still faces the right when she does. (00:58:30)
Continuity mistake: When Lou and Nick are playing pool in the bar, Lou goes to break the rack and misses. When Nick goes to break them, the balls are racked in a different pattern. (00:50:10)
Continuity mistake: In the final scene when Stark, Rhodes and the senator have a picture taken, Tony's jacket is first buttoned, then unbuttoned from the same viewing angle. (01:56:50)
Continuity mistake: When Ariadne wakes in the Snow Fortress and the floor goes from under her, we can see her gloves fall in to the crack but in a different camera shot of her we can see the gloves are now back near her head again. (02:12:20)
Continuity mistake: When the police car rolls out of the car wash, both passenger and driver's doors are open. When the shot changes to the deputy holding the rifle, the driver's door is closed. In the next shot both doors are open again.
Continuity mistake: When Royce kills the Predator at the end, he slices the head off, and it falls backwards, and the body falls forwards. One of the next shots now shows the head to now be in front of the Predator body.
Continuity mistake: Whenever Megamind or Minion uses the disguise generator, their normal eye colour always show through their disguises, such as when they both disguise themselves as the Warden (the Warden has blue/gray eyes while Megamind has green and Minion has brown). However, during the final battle, Minion disguises himself as Megamind but he has Megamind's green eyes instead of his normal brown eyes.
Continuity mistake: During the fight at the End of the Line Bar, Gem walks and stand next to Castor. Later she move to the left and sits on a couch for the rest of the fight. However, at the very beginning, right after Quorra jumps and protect Sam, there's a brief cut where we can already see her sitting there, too early.
Continuity mistake: During the car chase between Fitch and Diaz, Diaz's truck changes from a Suburban, to an Explorer, to an XL-7.
Continuity mistake: When Jake goes into the water with the tow rope around his waist, the rope is going over the top and through the railing of the boat. When he gets pulled away with the girl, the rope is seen down in the water.
Continuity mistake: In the first scene with Lucas in the race car, a curly also wants to get in it, but he is smashed to the ground by the driver who puts a brake. First we saw a lot of blood dropped from his head (on the starting grid), and in the next scene, shot with another camera, the blood disappears.
Continuity mistake: Jason spits blood onto Joker's chin which changes spot wise and shape wise by the next shot.
Continuity mistake: In the beginning, when Billy is talking to the bum (who later turns out to be Tawny), the bum has a glove on his right hand. When he reaches his right hand out to Billy and Billy gives him a subway token, there is no glove. It's back in the next shot.
