Audio problem: When the three villains fly after Superman, they all gather in a circle and one of them says "Wait there". It can't be Ursa because it is too deep and neither Zod's or Non's lips are moving so it is not them. So, who is it?

Visible crew/equipment: Lighting focus reflected on the cosmonaut's visor.

Deliberate "mistake": French officers and firemen speak in English between them.

Continuity: In East Houston, after Ursa says "your general wishes to speak" a sudden change of light takes place and her face swaps from shady to very bright.

Continuity: Before the East Houston scene, the rear view mirror in the cops' car is skewed in the outside shots, but straight in the ones inside.

Continuity: Man in a yellow shirt disappears after Ursa stops the bus in Metropolis.

Deliberate "mistake": When the villains rampage the White House, the flag's base remains on the ceiling, and the flag pole falls inside the house. So the final scene with Superman carrying the flag and its base as if it had been previously stolen or destroyed, is nonsensical, but it looks very patriotic indeed.

Continuity: In the Niagara falls, when Superman brings Lois a hot dog, the wider angle doesn't show a woman with a beige sweater coming form the right, who suddenly appears in the close up.

Continuity: When Ursa says "your general wishes to speak" her right arm changes the way it's open.

Continuity: After saving Lois in the river, Clark falls on the water and Lois cries "Here.", a split second later she has changed position, being now turned around and she has also moved 3 feet into water close to Clark.

Continuity: When villains fly through Perry's window the reflection of the lights disappear and the blinds flutter without any problem, revealing that the glass was taken out to allow for a safe jump.

Continuity: In the bar in East Houston, the man that challenges Ursa to arm-wrestle has his right arm and elbow on the table. In the next shot they're down.

Continuity: When Ursa sits down to arm-wrestle, a man with a red jacket who was sitting several feet to the left, suddenly appears on the back close to the guy with a Coors T-shirt.

Continuity: During the scene where villains arrive to the Daily Planet, Jimmy Olsen's haircut changes from long to very short.

Continuity: When Clark comes back to the diner to take revenge, a dish next to the bad guy suddenly appears.

Continuity: When Super arrives at the Daily Planet to defy the 3 villains, the outside shot shows three piles of books lined along the window. From the inside, all of the books are piled to the right.

Continuity: At the end of the movie, in the diner, the bad guy's food keeps changing appearance.

Continuity: When Superman reveals his identity to Lois, the liquid in the top of the lava lamp changes from filled to empty in half a second.

Visible crew/equipment: Crew members are seen wandering inside Lois' apartment at the end of the movie.

Revealing: When Non and Zod break in through the White House window, a black strap is seen attached to each one's body to help them descend safely.
