Continuity mistake: After the children are transported to Narnia, Edmund's hair is significantly shorter than it was while they were in England.
Continuity mistake: When Jake disguises himself as a messenger and enters a building intending to hack into a computer, he shows up at the ground floor lobby with his bicycle. Behind him, an Asian lady also turns from the lobby and walks past him. In another shot, the very same lady is seen entering the building from another entrance.
Continuity mistake: During the last fight with Darkseid, there's changes to what the farm looks like. At one point, instead of the windmill there's a building, which we never saw when Clark drove past the spot. And the overturned truck is missing in a several of scenes even though it should be visible.
Continuity mistake: When Solara hijacks the SUV after leaving George and Martha's, there are mountains that disappear from shot to shot. Right after Carnegie yells "Go back," you can see mountains in front of them. When Solara gets out and looks at them turning around, those mountains are gone. After she grabs the grenade and stands in the middle of the road, they are back. When she throws the grenade and Carnegie's vehicle swerves out of the way, the mountains are gone again. (01:27:30)
Continuity mistake: In the final battle scene after the Band reaches the canyons and are on a cliff overlooking the Guardians, you can obviously see that Twilight doesn't have his lute. After focusing on Soren struggling to remove the pot of tar, we see Twilight flying with Digger and Gylfie, but with his lute. Impossible to be so fast. (01:11:55)
Continuity mistake: When Ellie & Fiona are breaking into the garage to steal the gas tanker truck, Fiona's hands are by her side. The camera angle changes, and her right hand is up, holding her rifle strap.
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.
Continuity mistake: At the end, when Darcy and Gulliver are about to kiss before being interrupted, Darcy is holding the report in her right hand. When Dan walks in, the report is in her left hand.
Continuity mistake: During the last scene, the strands of hair that Edgar has running down his face/right cheek are over the top of his head during some shots. Edgar is holding a book between both hands, so not moving the strands himself. (01:16:19 - 01:16:55)
