Visible crew/equipment: When Superman and the super villain are fighting on the moon, when Superman flies in and lands at the beginning of the fight, you can see the cables that are suspending him.

Continuity: When Superman is walking with the kid towards the UN, they pass by a fire hydrant. In the immediate wide angle of the place the hydrant is gone, but reappears in the following shot a couple meters ahead of Superman.

Continuity: Two firemen are seen away from their truck, but when the angle changes six firemen have appeared seemingly from nowhere.

Continuity: When ever there is a shot of Superman flying taken from directly in front of him, on a bluescreen (Watch out for the oh-so-visible black outline and loss of colour), it's always the exact same shot. Obviously the producers could only get one day with the blue screen, then.

Continuity: Nuclear Man dents the floor with his footsteps, but in a wider angle the floor is intact.

Continuity: When in the subway, Superman is standing by a 6 foot poster of the Statue of Liberty. When the shot changes to a flying Superman, he is a third of his size and the poster is huge.

Factual error: The Sun Man takes the publisher of the newspaper out into space. Humans cannot breathe in outer space. Even if they could, wouldn't she burn up in re-entry? It can't be Superman's powers are transferred to someone he's touching, otherwise in the second film he could never have crushed General Zod's hand...

Continuity: When Nuclear Man arrives on Earth, he enters a shady place which makes him loose his power and cools his body, producing some frozen-like smoke. The next two times that he enters a dark place (inside the elevator and in space) he doesn't produce the smoke. FX budget problems here?

Continuity: When Nuclear Man fires at the fire truck a short piece of hose comes out. A second later, in the following shot, the hose is 10 meters long and all over the place.

Continuity: When Lacy is in outer space grabbed by Nuclear Man, she slides down dramatically and grabs on his wrist. Half a second later, the sliding effect is gone and she is now floating relaxed, grabbing the upper part of his arm.

Continuity: In the barn, Superman puts a glowing crystal inside a pocket. A frame later it disappears.

Continuity: Before lava covers the Italian village, furniture under the two arches on the right, as well as a vase, cart wheel and table on the left disappear between shots.

Continuity: Luthor holds a sealed champagne bottle with both hands on the neck of it. He doesn't move them, nor his shoulders, nor do we hear any sound revealing that the bottle's being opened. However, when Luthor leaves, the bottle's seal appears opened and 20 centimeters away when the scene ends.

Continuity: A couple walks behind the hot dog stand in the same direction twice in less than half a second.

Continuity: Shortage of extras in this film: Inside the UN hall, the arab man that greets Superman is the one that a second before was in the entrance.

Continuity: The shape and size of the volcano is totally different between the moment when Nuclear Man enters it, to when it erupts.

Continuity: While the people in the village are watching the lava flow down the streets, the first shot shows them to the right of a wooden door. A frame later they are positioned several feet further, close to a big green plant.

Continuity: When the lava is flooding the village, a big green plant appears close to a priest. When Superman cools the lava and the smoke goes away, we see that the plant is much smaller and less leafy.

Continuity: Behind where Nuclear Man lands there's no school bus on the wide shot, which is a matte painting, but a frame later one appears and stays there for the rest of the scene.

Continuity: When nuclear Man bursts the cab's hood, the radiator explodes and vanishes. A second later it's back on.
