Corrected entry: In the interview with Lois Superman says he never lies. He also said he is 27 years old. In an earlier scene, Clark Kent left the confines of the earth with Jor-el at the fortress of solitude, as an 18 year old high school graduate. When he returned to earth, 12 earth years have passed. 18+12=30, not 27.
Corrected entry: When there is a big explosion at a plant and Superman flies in to save the day, all he does to stop the explosions is pull down the toggle of a huge switch situated on the wall; if this is all that was needed to stop the explosions, then why didn't one of the workers do it, and save Superman the trouble of flying all the way out there to do something which one of the workers could have done easily.
Corrected entry: The burglar is heading upwards when he meets Superman on the side of the building. He's already got stolen jewellery on him when Superman hands him over to the nearest cop on the ground. Wouldn't he have been heading down the building if he'd already committed the burglary?
Corrected entry: When young Clark Kent is being taken on a journey by his deceased father, the journey ends with Jor-El saying, "By the time we return to the confines of your galaxy, twelve of your years will have passed." If Clark was gone twelve years, how could he have managed to get a job at the Daily Planet? There would have been a background check to see which journalism school that Clark went to as well as college and also to see if he had other jobs, yet he simply gets the job without a problem. All of the people that Clark grew up with would probably be curious as to why they haven't seen or heard from him in a long time as well.
Corrected entry: In the scene where Officer Mooney dashes into his precinct to report that Superman has hand delivered him a burglar - the officer tries to say 'In big red boots' - but actually says 'Big red ROOTS.' Incidentally where's the burglar? He wasn't there, or tied up outside with the villainous boat crew.
Corrected entry: When there is a big explosion at a plant during the earthquake, and Superman flies in to save the day, all he does to stop the explosions is pull down the toggle of a huge switch situated on the wall; if this is all that was needed to stop the explosions, then why didn't one of the workers do it, and save Superman the trouble of flying all the way out there to do something which one of the workers could have done easily.
Corrected entry: When Lex is detailing his plan to Superman over the map on the floor, Otis puts an overlay of the San Andreas fault over California. A few moments later, Otis drops a second overlay on top of the first, this time of the revised coastline Luther is planning. Superman and Luthor talk for a few moments, and Lex tells him it was hard to find the ideal spot to hit with the missile. He then strikes the floor with his cane, cracking the glass of the map, but it's the first overlay that is cracked, and the second overlay is suddenly gone.
Corrected entry: After Clark and Lois leave the Daily Planet building after Clark's first day, one quick cut later, they are in Chinatown (I realize Metropolis isn't literally New York City, but since the movie makes no attempt to hide that the Metropolis scenes were filmed in NYC, it seems legit. Even if you discount that, Lois and Clark still managed to be in a very noticeably different part of Metropolis within seconds). (00:55:50)
Corrected entry: When Johnathan Kent has a heart attack and falls to the ground, Clark's mother yells out "Johnathan!" There's a reaction shot of Clark inside the barn with the dog, then it cuts to a wide angle shot. Clark runs out of the barn, but the dog is now outside towards the back, running along the outside of the building to catch up with Clark. Not nearly enough time between the two shots for the dog to run all the way out the back of the barn and around the side.
Corrected entry: When the thief is climbing the building, you can see the panels that he is climbing on are not made of glass as the don't cast any reflection. It is just some kind of black plastic.
Corrected entry: This occurs just after Superman saves the town in the valley from being washed away by the flood from the broken dam. He stops and listens, and hears Lois. Just before the scene changes and he goes to rescue her, his lips move as though he is saying "Lois" but no audio is heard. No subtitle is on the DVD either.
Corrected entry: When Superman saves the train from derailing during the earthquake, he places his body between the tracks, hold up one rail with his right hand, and uses his left arm and side as the other rail. But even Superman can't change physics. Train wheels have a flange that goes on the inside of the rail to keep it from slipping off the rail. (Go look at your model train set). Since Superman is indestructible, this flange would hit him and derail the train (Perhaps this is why he ducks his head).
Corrected entry: When Lois Lane falls out of the helicopter we assume the building she is on is the Daily Planet since we have no indication she left, and Clark exits the same building. However, the building differs from the one pictured before the opening credits (they have different roof styles).
Corrected entry: Towards the end of the movie, where Clark is racing (or flying) after the rocket to save Lex's girl's mom first, it seems obvious how he is struggling to catch up to the rocket. But then later, he is circling the earth to 'rewind' time, to save Lois... he must have easily been going ten times faster than he was when trying to catch the rocket.
Corrected entry: The first time he catches Lois, he doesn't break her fall at all - he just stops her in midair, meaning that there'd be no difference from if she'd hit the pavement.
