Continuity mistake: After Batman shoots Reverse Flash through the head, Flash rushes over to Batman and catches him before he falls over from his wounds. As Flash is lying him down slowly, there is no blood on Batman's face. It then cuts to a close up as Batman reaches up to pull off his mask and there is suddenly blood on his lips and chin.

Continuity mistake: While Pooh and his hungry tummy are searching for honey Pooh finds himself at Owl's house, and in the first wideshot we can see the wood sign that reads "Dont nock plez ring" with nothing above it, but once Pooh reads the sign suddenly Eeyore's tail is hanging above the sign as a bell-pull.

Continuity mistake: As Lex and Joker are talking on the bridge between two towers of Arkham Asylum, Joker is shown standing in the middle of the bridge. But when the guy on the intercom announces there is an escape going on, the camera changes angles and suddenly Joker is right next to the edge. (00:19:20)
Revealing mistake: As Elsa sings "Let It Go" she pulls her hair into a long braid going down her back. She pulls it with her left hand from behind her to in front, but the end doesn't flip over her shoulder, she just pulls it straight through to the other side without going over the top. (00:34:10)
Factual error: When Chicken Little is in his bedroom, after he scored during his baseball game, he looks into the spoon he is using as a microphone to see his reflection. He looks into the side that is curved away from you. When you look at that side of a spoon your reflection is upsidedown, but Chicken Little's was right side up.
Continuity mistake: After Ralph destroys the cake and it goes all over the place, we cut to a wide shot. In this shot, to Gene's right, there is a small amount of cake on the floor. In the following shot, the amount of cake has doubled. Also after Ralph destroys the cake Mary is holding the people that were on top of the cake even though Ralph just destroyed them. (00:13:10)
