Visible crew/equipment: When Lois pulls up to the house where the blackout was traced to, she hears some music coming from the boat down at the dock. As the camera pans upwards over the car, as she steps out, the whole camera and a crew member are reflected in the side of the car.
Deliberate mistake: When Lex tests the crystal fragment, it knocks out all the power on the airplane Lois is flying in, yet the flight attendant's amplified voice can still be heard over the speakers. (00:30:40)
Continuity mistake: In the scene where Lois Lane is holding her son as Lex Luthor is revealing his plan to her the ring on her left hand switches back and forth between her middle and ring fingers. (01:25:05)
Continuity mistake: Near the end of the film when Lois makes to leave the hospital room after visiting Superman, she takes hold of her son's left hand with her right - meaning he should walk out whilst at her right side, furthest away from the hospital bed. In the next shot, both Lois and her son have swapped positions. (02:00:00)
Other mistake: The text of the German news is wrong. It is titled "Fensterputzer halten an ihrem Lebemfest" (Window cleaners hold on for their lives). It should be "Leben fest". Also "Newsdirek" is wrong, it should be "Newsdirekt" or better "News direkt."
Continuity mistake: In the scene where Richard finds Lois and the son on the yacht, he hugs the boy and you can see that one of the drawers is open. When he looks up at Lois, the drawer is now closed. (01:46:30)
Revealing mistake: Just before the end credits, as Superman is flying past Metropolis and into space, watch the car headlights in the background. The background shot is blatantly sped-up by a large amount, as all of the cars appear to be travelling at huge speeds, even in a traffic jam.
Revealing mistake: During the airplane mishap where Lois is pinned to the ceiling, notice how the force is strong enough to hold her there, but both her hair and ID badge still hang down. (00:38:25)
Continuity mistake: When Lois Lane and Lex Luthor are talking on the ship, the knot on his tie changes throughout the scene.
Factual error: About 11 minutes into the film, Luthor's yacht is seen in heavy seas in the Arctic. The helo on the helo deck has its rotor blades extended. This would cause immediate damage to them so is never done, even on carriers - the helicopter wouldn't be able to fly properly. (00:11:20)
Continuity mistake: When Superman grabs the falling sculpture-globe the aerial view shows the hood of the cab on the left is undamaged. From a ground level view, the hood is severely damaged. (01:44:35)
Continuity mistake: In the scene where Superman is trying to prevent the plane from crashing he is holding the nose of the plane and bits of it start to crumble in and fall apart or away. Once the plane is safely on the ground within the ballpark the scene shows the plane from the side where there is no damage to the nose. (00:40:15)
Continuity mistake: In the sequence with the kryptonite continent, Superman plunges under water, when he comes back up, his hair is soaked, then throughout the next few shots, it switches back and forth of being out of place and being "super" hair.
Factual error: Jimmy tells Clark that Luthor was freed from jail because Superman didn't appear when the Court of Appeals called him as a witness. Court of Appeals rulings are based on the facts in evidence from the previous trial, and nothing else. No new evidence or testimony is allowed.
Continuity mistake: Before the earthquake, the radio in Ma Kent's changes positions between shots, and a table cloth appears under Ma Kent's reading glasses.
Other mistake: In the credits, just before the listings for the transportation crews, "Post production" is misspelled as "Post Poduction".
Visible crew/equipment: In the scene where Martha Kent investigates the crystal ship, there is a fuzzy outline of a crew member behind the truck.
Continuity mistake: In the scene when Superman is entering the baseball stadium from above holding the 'plane, we see a quick shot looking down from above the 'plane. The field is empty of players.
Continuity mistake: When Superman is flying over the sea trying to locate Lois, his hair is fluffy. He suddenly stops and there's a brusque cut where a close-up of him shows his hair brushed and perfect.
Continuity mistake: In the scene where Lois and Jason are going to the hospital to visit Superman, Jason's hair is wet outside as they are walking toward the hospital. Once inside however, his hair is dry.
Chosen answer: The chunks that fall off the "new" land are actually bits of the earth's crust. Superman had actually drilled himself way beneath the "new" land (under the bottom of the ocean floor) so that he was not in contact with the Kryptonite infected crystal land, so that he could lift it up and get rid of it. It is this earth crust that falls off slowly, revealing the kryptonite crystals beneath, and this is why his strength slowly gets taken away as he flies higher, until there is too much exposed and he loses all his strength.
