Continuity: When Superman falls on the Marlboro truck, the part reading "Ma" gets more crumpled after Superman leaves the truck compared to when he landed on it.

Continuity: In the part where the 3 super villains attack the astronauts on the moon there is a scene where the Non character moves the lander with the astronaut still inside. Non is lifting up the lander leg and there is a shot of the astronaut inside a collapsing cabin. It is like there is something crushing the roof inwards but all 3 super villains are accounted for with Zod sat in the moon buggy and Ursula stood next to him while Non is still holding the lander leg. This happens twice in the space of a few seconds before Non jumps on top of the lander to crush it.

Audio problem: In the Fortress of Solitude, when Superman kneels before Zod, we hear Lois sobbing, but her mouth and body don't move.

Continuity: Inside the bar in East Houston, Zod pushes a man backwards, but the next shot shows the man flying as if he had been thrown upwards.

Continuity: When the villains are being judged, for a brief second they change positions, Zod being on the far right instead the far left.

Plot hole: When the villains rampage Perry's office and later fly through the windows, no one ever comes close to the pillar between the windows, nor any violence is done around it. However, after the fly away the pillar falls down on the street.

Audio problem: At the Eiffel Tower, after Lois asks the French officer if the terrorists have the proper equipment, his voice is heard but from a side view his mouth and jaw don't move.

Continuity: In East Houston, behind the man lifted by Zod, there's a man standing several feet away from a car. A frame later he's very close to the car.

Revealing: When Non goes through the pavement, the hole reveals it's a foam made floor.

Continuity: When the News Beat reporter arrives, the shadow on the satellite dish changes significantly in a couple of seconds.

Continuity: When Zod burns several cars, the street is filled with parked cars and people. From Superman's point of view the street is empty and you only get to see the three burning cars and a couple of cabs.

Audio problem: When the villains blow the people back in Metropolis, all the ones near the KFC restaurant (the waitress, the guy in the phone booth and the couple) shout or make comments but their mouths either don't move or are not in synch.

Continuity: When Ursa is moving the helicopter around, the sky keeps changing from sunny to cloudy.

Revealing: When Zod jumps out of Perry's window he falls down, revealing its a stunt from a ground level window. The outside shots however, show Zod flying up and straight.

Deliberate "mistake": Luthor and Teschmaker visit the North Pole protecting themselves against the cold. Lois manages to wander around with a mere, but sexy, shirt.

Revealing: Before the villains change the faces on Mt. Rushmore, the original ones (which are a matte painting) have a greenish look. Definitely not like the real sculptures.

Revealing: At the beginning of the movie, we see the three villains in front of several backgrounds. In most of these backgrounds, their outlines are fuzzy, indicating that they are actually standing in front of a green screen.

Other: In the scene where there are multiple Superman's in his home, Lois Lane runs to one of the fakes. It seems as if she is the fake because her image becomes slightly transparent as she runs through him.

Continuity: When the elevator falls down the shaft with Lois trapped underneath, Superman flies up to rescue her. He stops the elevator, and when he does, Lois climbs off from the bottom of the elevator and runs to hug him. Problem is, when she climbed off the bottom of the elevator, there should have been nothing but air underneath her.

Visible crew/equipment: When the super baddies arrive on the moon and encounter the astronauts, the girl Kryptonian kicks one of the astronauts into space and you can see the strings around his waist as he floats away.
