Plot hole: When Nuclear Man 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 Nuclear Man was talking about? There was no indication that Superman knew that Nuclear Man was looking for Lacy.

Continuity mistake: When Superman is walking with the kid towards the UN, they pass by a fire hydrant and one can see the street ahead is empty. A shot later another hydrant suddenly appears.
Suggested correction: The fire hydrant in question is actually two. The one they first pass is slightly faded with chipped paint. The next shot you see a different one that is fully painted red. The next shot shows the crowd passing the first hydrant seen.
Plot hole: Superman manages to find bricks to rebuild the Great Wall of China. While it's true that he could have created the bricks from stones, the humongous explosions of the wall, and the vast grounds surrounding the area, show that there is no place, no material, and no way even for Superman to create 1,000 bricks from nothing.
Plot hole: Superman dropping Nuclear Man in the area of a nuclear plant would have made him much stronger, since that is giving him a lot of nuclear energy. Instead he is killed.
Suggested correction: Dropping nuclear man in to a nuclear power plant isn't as silly as it seems, assuming that the nuclear power is far greater than nuclear man he would simply be absorbed by it rather than growing stronger.
That never got shown and the fact that he was able to make a volcano erupt speaks volumes.
Factual error: The Russians launch a missile which stands upright on a truck. The energy needed to send it beyond the atmosphere would need such a huge fire blast that it would've caused a big explosion when in contact with the truck's petrol deposit.
Suggested correction: The RT-2PM "Topol" nuclear missile was carried on a MAZ-7917 mobile launcher - essentially, a huge truck - from which it was launched. The truck was not damaged by the rocket exhaust.
That's exactly my point. Plus, given that the truck is a blatant miniature prop.
Suggested correction: Standard hero response, Villain wants something Hero denies it. This could be replaced with anything. "Where is the crystal" "You'll never find it" Doesn't matter that he knows who or what it is. Villain wants it, tell him he can't have it.
False. This dialogue is part of many deleted scenes involving a plot where Nuclear Man searches for Lacy.
