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 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.

Visible crew/equipment: When Nuclear Man turns Luthor's assistant around on the air, supporting wires are visible. Submitted by Sacha

Continuity: Superman traps the supervillain (whose power depends on sunlight) inside of an elevator to incapacitate him. Superman then ripped the elevator out of the building. He then plants it on the far side of the moon. Later on, sunlight starts to shine into the elevator through a slit at where the doors meet. The villain of course recharges and comes after Superman again. Now, if light could get through that crack there, then why couldn't it get through when the elevator was ripped out of the building in BROAD DAYLIGHT?

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. Submitted by Sacha

Continuity: When Superman takes off after saving the boy in the Great Wall of China scene, you see him heading up, as if leaving, but in the next cut, he's on the ground next to the wall.

Other: In the rest of Superman movies, whenever he used his eyes to do some trick a beam came out. In this (really cheap) movie the beam is gone. Submitted by Sacha

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. Submitted by Sacha

Revealing: While Nuclear Man and Superman are falling off the balcony, their skin switches from pink to natural. When Nuclear Man finally flies away he looses all of his colour and becomes semi transparent. Submitted by Sacha

Plot hole: After Nuclear Man slides down the chimney of the Nuclear Plant the lid of the reactor is open and then automatically closes. This whole premise is totally absurd, not only for security reasons, but for logical ones too. Submitted by Sacha

Visible crew/equipment: In the quarry, when the cops' car flies up the air you can see the ramp used to lift it on the lower left side of the screen. Submitted by Sacha

Continuity: While Superman is taking the Statue of liberty back to its place the sky keeps changing between violet and blue, sunny and cloudy. Submitted by Sacha

Revealing: Watch the moon fight between the two supermen. In one scene, Superman charges nuclearman and you can see the backdrops flutter if your monitor brightness is high. Submitted by Joseph Z

Revealing: When Superman and Nuclearman are fighting for the first time in outer space, you can see them both standing on a small platform.

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

Factual error: Superman and Nuclear Man fly around the world fighting at incredible speed. Everywhere they go, including places as widely spread as New York and China, it's daytime.

Plot hole: When NuclearMan sees a picture of Lacy Warfield on the newspaper he decides to go after her. When confronted by Superman he asks "Where is the woman?" Superman responds that he'll never find her. How could Superman know which woman NuclearMan was talking about? There was no indication that Superman knew that NuclearMan was looking for Lacy.

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. Submitted by Sacha

Visible crew/equipment: When Nuclear Man's laser beams send Superman flying away on the moon, the shadow of the crane moving him is visible. Submitted by Sacha
