Continuity mistake: The kid fell backwards off the ledge and down toward the falls, but the distance shot he's face down rather than face up. It's also easy to see that it's a dummy because the hair color is different, as well as the body structure and limb movements are all wrong for a human.Movie Nut
Continuity mistake: During the Marlboro truck scene, a woman with a violet dress and curly hair is inside her car laughing at the fight. This lady appears in almost every single angle of the flying sewers scene with no continuity at all: sometimes standing, sometimes falling, other times somewhere opposite to where she was before.Sacha
Continuity mistake: Right after Ursa cries "Superman" and is about to throw the sewer lid at him, a man with a white jacket and a big afro runs from right to left and hides behind her. When the angle changes, he is on the very far right side of the street, many meters away, running towards Ursa, repeating all previous movements.Sacha
Revealing mistake: There are two times in the New York battle when you can see the actors are being filmed in front of a screen: 1. when Superman kicks Non, Superman in on film and Non is hovering in front of the screen. 2. When Ursa is flying towards Non and Superman with the flagpole, she is hovering in front of the screen.
