Revealing mistake: When evil Superman moves the Pisa tower, there's a protruding peak on his cape, seemingly a flying wire or some mechanism to make it move.

Sacha

Revealing mistake: When Superman gets blown away by the bombs, he is being smashed onto the rocks. You can easily see that the rocks aren't real, but also that when he rises up again, you can see the cardboard rocks dent.

Revealing mistake: When Evil Superman blows out the acid from his hands, the tube used to throw the liquid can be seen for a brief second standing out from his finger (hard to notice but it is there).

Sacha

Revealing mistake: When the two Supermen are fighting in the scrapyard: As evil Superman comes flying out of the acid with his hands cupped, look at his cape. It is wrapped around the front of his waist and legs, not flapping backwards like it would be if Supes was flying forward at speed. Evil Superman is also completely dry during this shot (NOTE: Superpowers have nothing to do with this). This reveals the fact that it was shot with Christopher Reeve (or the stuntman) falling backwards into the vat, then shown in reverse.

Revealing mistake: At the chemical plant, while Superman is landing Jimmy Olsen, the crane that holds them in the air casts a shadow on the green truck behind.

Sacha

Revealing mistake: When the two Supermen are fighting, towards the end Clark chokes evil Superman. In this shot you can see where they cropped a stuntman's hands in the place, where Clark's hands would be, in order to have Christopher Reeve play both parts.

Revealing mistake: When Gus flies off with his skis, note that the wooden lattice is already broken before his crash to allow for the stunt.

Sacha

Revealing mistake: During the Pisa tower scenes, the sky is always the same, plus the balloons in the stall have the exact same position, revealing not only that the shot is a chroma, but that both scenes were shot the same day.

Sacha

Revealing mistake: After throwing Clark into the compacter, Evil Superman flies to the control booth. As he walks through the door, the background can be seen through him.

Movie Nut

Revealing mistake: As Evil Superman quips to Clark about wanting to fly, as he struggles Clark's left shoulder goes a little transparent, showing his image was superimposed over the stunt actor.

Movie Nut

Revealing mistake: After Clark defeats Evil Superman, he flies to the Statue of Liberty. The whole landscape is a still image with the ripples and the boats completely static.

Sacha

Revealing mistake: When the firemen's truck runs out of water there's a close-up of the level meter and it reads "Pierreville fire trucks Ltd. Camions a incendie" revealing the scene was shot in Canada.

Sacha

Revealing mistake: When Clark's sneeze launches the bowling ball, the ball casts no shadow, revealing it's a superimposed image.

Revealing mistake: When the phone booths fall they don't have any cables attached underneath, revealing they're props.

Sacha

Other mistake: Towards the end of the movie, when Superman drops Gus off at the coal mine, Gus begins talking with the coal miners about him and Superman. He then rips open his shirt (as if he had a Superman costume on underneath). How did Gus know that Clark Kent tore his shirt like that in order to change into Superman, or keeps his suit under his clothes at all? The only people who know this fact are the ones who have seen the transformation from Clark to Superman, i.e. the audience.

Question: How come Superman is so nice to Gus at the end? He was working with the baddies, he created a computer and the Kryptonite to kill Superman! Yet Superman is totally cool and even asks the coal miners to give Gus a job. Did I miss something?

Answer: The only reason that Gus was working with Ross, Vera and Lorelei was because he stole money from the company he worked at. To avoid going to prison, Gus was forced to do anything that they wanted. After realizing that his computer was designed to do anything it was ordered to, including killing Superman, Gus removed a small screw which shut down the power momentarily but, after the computer brought itself back online, Gus attempted to destroy it with an axe to save Superman. Superman saw this and realised he was wrong about Gus and after the computer was destroyed decided to help Gus find a job.

That makes sense, thank you! Been bugging me for years.
