Frequently Asked Questions
Either one of two things will explain this. One, he didnt cut the hair itself, but instead simply cut the metal around it that the hair was attached to. Two, even extremely strong material like a strand of Superman's hair, being so thin, is able to be cut with a good pair of wire/bolt cutters.
This is not depicted in the movie; however, as it was Superman, it is safe to assume that he used his superpowers to construct it.
The Lex Luthor portrayed by Gene Hackman is not exactly the same Lex Luthor from the comics. Gene's Lex Luthor is really a caricature similar to an evil/eccentric Donald Trump. He surely surrounds himself with idiots only to accentuate his intellegence and boost his ego.
It was presumably Superman himself using his superpowers (somehow).
1. Nuclear Man takes Lacy into space where there is no air, and yet she stays very much alive the whole time. Possibly explained by the supers projecting an atmospheric shield around themselves. Remember this was 1987 and the script writers clearly weren't comic book geeks or wholly knowledgeable about comic book physics.
2. Numerous scenes of Superman and Nuclear Man, while in space, very clearly breathing and/or talking. They may be able to fly and hold their breath for a long time, but this doesn't mean they could possibly talk or breathe in the vacuum of space. We also see Superman's cape blowing in the wind while he's in space a number of times.
3. Metropolis is supposed to be its own fictional city somewhere on the East Coast; however, all the views shown clearly reveal it to be New York (The Statue of Liberty, which appears in the first film as well; Empire State Building; etc.). This is can be explained by the fact that in the DC Universe, Metropolis is often depicted as being analogous to New York City.
4. Superman may be extremely strong, but if he were to exert the amount of force needed to push a large body like the moon, such a localized amount of force on the surface could not possibly cause it as a whole to move. It would in fact cause a localized dispersal of material on the surface and cause him to "burrow" down under the surface. (For example, think what would happen if you tried to move a car by pushing it with a thin metal rod). Also, the moon being moved so rapidly all of a sudden would have a very adverse effect on the Earth in regard to the ocean's tides. Not really a plot hole so much as an ignorance of real world physics for the sake of a larger-than-life movie. Note that Superman breaks the laws of physics himself simply by existing.
5. How exactly was Superman able to repair the damage done to the Great Wall? He doesn't normally have telekinetic powers, and even if he did, would he able to put back together the jagged, uneven, broken pieces of stone into the nicely carved bricks they used to be? A matter of convenience here. The writers wanted to show him being the good guy so they arbitrarily gave him telekinetic powers to counter the destruction Nuclear Man did.
6. Whenever Superman takes someone such as Lois flying, why are they not affected by the extremes in atmosphere? (It's very cold with much lower levels of oxygen high up in the air). Also, they often end up flying exactly parallel to him even though hes only hanging onto their hand. Shouldn't they be dangling below or behind him? Again, this is simply writers ignoring physics for the sake of "good visuals".
7. An object as large as a building (i.e. the Statue of Liberty carried around by Nuclear Man and later Superman) could not be held up horizontally by only one small area a few feet wide on one of its ends. Such a huge amount of weight throughout the length of the building would cause too much stress along the unsupported areas and cause it to break apart. See above explanations.
An explanation was given in the script, though this motivation never made it into the film:
371 THE NUCLEAR MAN
His genetic memory kicks in. This is the woman he fell in love with at the disco. His entire demeanor changes as bold desire courses through him. Again, his eyes glow red. He reaches out gently to touch Lacy Warfield's ([link]
Despite the fact that 40 minutes of footage were cut out before the movie was released, there still exist two different versions of the movie. In the US version, two scenes were not shown that are included on the German VHS release. However, all later DVD and Blu-ray releases used the shorter US Master, thus the two scenes are missing as well. According to IMDB the longer version is a special TV version which was made for American TV channels. This wouldn't be an unusual thing, since several movies had a longer TV version so that the channels could air more commercials. The two scenes that used to be in the German version are also included in the deleted scenes section of the DVD.
