Corrected entry: When Luthor is showing Lois maps of the new continent he intends to create, the final map initially shows a large 'state' marked out in the centre of the star-shaped island, with several other territories making up the points of the star. The shot changes as Luthor heads above deck, and we see the map behind him, but now the borders of the territories have changed and the central state takes up less space.Jez
Corrected entry: On Lex Luthor's Russian-made missile launcher, the second button from the left is labelled "otkaz", which is presumably intended to mean "abort". The correct word would be "otmena". While "otkaz" is a general synonym, in a technological context it means, rather unfortunately, "equipment failure".
Corrected entry: As Superman is shown flying literally 3 feet or so above the surface of the ocean, the water is not affected at all. It was established in the beginning of the scene that he was exceeding the speed of sound, and anything flying at that speed that close to the surface of the water would produce a wave/rooster tail of at least 20 feet or so.
Corrected entry: When the bank-robber with the Gatling gun shoots Superman in the eye from close range with his pistol, the bullet flattens and deforms upon impact with Superman's eye, and then falls lazily to the ground directly at their feet. The bad guy even watches as the bullet falls. This shouldn't happen: The bullet should have ricocheted off of Superman's eye with a lot of latent energy since none of it was dissipated upon impact. The bullet would have violently ricocheted away from the area just like the hundreds of bullets fired at Superman from the machine gun did. Also there is no way that any human could react fast enough to actually watch a ricocheting bullet from that short distance.
Corrected entry: Jor-El's voice repeats something from the first film, that "by the time you get to Earth a thousand years will have passed", meaning that while his aging will be vastly slowed, the journey will take a thousand years. Yet Superman goes there and back in five years of real time using the same technology.
Corrected entry: Superman's strength and other superpowers seem to oscillate a lot between scenes in the movie, and for no good reason. Towards the end of "Superman Returns", he is shown lifting an entire landmass out of the ocean, and pushing it into outer space, all while being exposed to Kryptonite. He is also capable of showing up anywhere in the world nearly instantly, as a reporter comments. Yet in one of the first action scenes, he struggles trying to catch up with a plummeting airplane, and has a hard time slowing it down, managing it just before the plane hits the ground. This should be a trivial task for someone of his abilities, yet no in-movie explanation is given for such poor performance. Of course, the real reason is obvious - the plot requires that Superman saves the day just in the nick of time, to create cinematic tension and resolution.
Corrected entry: In the scene where Superman is lifting the newly crated island to space, he stops pushing it, and the island continues into space. Then suddenly, as he looses weight and mass (because the island is gone), Superman falls down towards earth. If he does, so should the island. Alternatively, if the island continues into space, so should Superman.
Corrected entry: Why does gravity seem to be either on or off while on the airplane? Just leaving the atmosphere would not suddenly cause things to start floating as they do.
Corrected entry: In the scene where Superman lifts up the sunken yacht in order to save Lois and her family it shows when he lets go that he was holding that entire half of the ship completely out of the water with one hand. This is impossible, assuming that he was able to lift that much that spot on the ship could not hold that much weight without ripping away from the rest of the ship.
Corrected entry: As the plane falls to Earth toward the start of the movie, there is no sign of re-entry heat being built up on the plane do to air resistance and air compression beneath the plane.
Corrected entry: An electromagnetic pulse (EMP), such as those caused by the crystal reactions, affects unshielded electronic equipment because it induces a voltage surge in their components, effectively 'frying' them. All affected devices are damaged permanently and would never work again, not even after a few minutes, as they portrayed to do so here.
Corrected entry: In the plane sequence the whole weightlessness is wrong. When the plane is high in the atmosphere the people inside it will still be under the effect of gravity (when the film shows no gravity) and then as it falls you would get effective weightlessness as everything falls at the same speed (yet the film has the gravity switched back on).twine42
Corrected entry: Lex states that the crystals just need water to grow meaning that the new land must be somehow made from water molecules. In that case the land is effectively solidified water, lifted out of the ocean, meaning the worldwide water levels would drop, not rise. None of the flooding could ever happen.twine42
Corrected entry: Near the end of Superman when he reaches the new island he confronts Lex and suddenly becomes weak because there is Kryptonite near him. This makes him so weak that Lex and his 2 goons can beat him up and gives Lex the opportunity to stab Superman with a sharp piece of Kryptonite, Superman is then pushed into the water but manages to lift the island up (although being stabbed with Kryptonite) even though a large piece of Kryptonite is right in front of his face. Superman lifts the island into space before falling.
Corrected entry: When Lex reads the 'Superman is back' Daily Planet, it is dated something like September 16, 2006. Later, we see Superman on a store CCTV camera which is dated July 25. Then, on the 'Superman is Dead' / 'Superman Lives' Daily Planet covers the date reads something like September 27 2006. The date constantly changes.
Corrected entry: During the airliner crash sequence, there are two cuts to the cockpit after both wings (and engines) have been torn off. In one, you can hear the flight deck computer saying "Overspeed. Overspeed". Later, after the plane is on the ground, you can hear "Fly up. Fly up." Both are valid warnings at the time, but without engines there is no power for these systems, and exterior shots don't show a ram air turbine deployed for backup power.
Corrected entry: During the out-of-control airplane scene, Lois (and other objects) are violently thrown around inside the plane. There are no bumps, bruises or scratches on any of the passengers or their clothing, and every hair is in place on Lois once the event is over.
Corrected entry: Throughout the film, Superman's suit & cape are as impervious to damage as the man himself, even withstanding a full-on volley from a minigun. Yet when he is taken to hospital, the medics are able to rip open the chest area as if it was normal material. It can't be because his powers are waning, as they can't puncture his skin with a needle.
Corrected entry: During the flashback, when Clark is learning how to fly he appears to be between 11 and 13 years old. In these scenes he is wearing glasses. In Superman I it is established that Clark did not wear glasses until he was a grown man. He is seen without glasses in Superman I as a high school-age teenager. He adopted the glasses as part of his "disguise" when he went to Metropolis.Jason Hoffman
Corrected entry: At the beginning of the film, Clark wakes up in his bed. There is a close-up of his eyes. They are brown. However, during the rest of the film, Clark's eyes are blue.
Corrected entry: When the series of tremors causes the globe on top of The Daily Planet Headquarters to topple and fall, Superman catches it and places it on a car. When he flies away that night, at the end of the movie, and the camera spans Metropolis behind him, it sits in its original position on top of the Headquarters.
Corrected entry: When Superman is flying the new continent up and away from Earth, we see some Kryptonite right next to his fingers (actually, it's everywhere). It's already been established that Superman being near the Kryptonite on this continent will remove his powers, so he should not be able to fly, or be able to use his super strength.
Corrected entry: A powered shuttle destined to leave the atmosphere could not be launched from the top of a flying jetliner for the simple fact that it would never be able to achieve escape velocity while flying. The speeds necessary to achieve sub-orbital injection require a near-100% vertical climb at speeds of well over 9,000 mph. If a shuttle flying at anywhere even near that speed tried to increase its rate of climb from horizontal to vertical, the aerodynamic forces encountered would destroy the airframe of the shuttle. Also, the shuttle's engines use a hypergolic chemical fuel reaction and the resulting thrust is so great that the the jetliner would have been instantly destroyed from the acceleration forces when it was still attached the the shuttle.
