Superman

Factual error: When Clark speaks to Jor-El for the first time in the Fortress, Jor-El says "I will have been dead for many thousands of your years..." Fine in theory - Baby Kal-El travelled to Earth at above light speed so time passed differently for him. However, as such, wouldn't Jor-El have seen Earth as it was thousands of years ago? Which also makes there a problem with all the things Kal-El was taught during his voyage to Earth, as Jor-El references Einstein by name, for instance, and he would not have existed at the point when Jor-El sent him to Earth.

Factual error: When Superman is turning back time by flying around the Earth, right before he starts orbiting the Earth is spinning way faster than it actually should be. If the Earth actually spun that fast, a day would pass by every 1.44 minutes.

Trivia: Jeff East, who plays teenage Clark Kent, was dubbed over with Christopher Reeves' voice. The only time Jeff's actual voice is heard is when he shouts in excitement after jumping past the speeding train.

Trivia: The famous (or infamous) New York City blackout of 1977 occurred during location shooting for "Superman." According to director Richard Donner, cinematographer Geoffrey Unsworth mistakenly believed he had caused the blackout by plugging in a spotlight to a lamppost while filming.

More quotes from Superman

Question: When Superman went back in time to save Lois, doesn't that mean that the people that he had originally saved are now doomed to die?

Teru_Kage

Chosen answer: No. Because the version of him *before* he time-traveled is still out doing those things. The REAL question is, what happens to that Superman, seeing as Lois no longer dies and he has no reason to travel back in time.

JC Fernandez

Answer: There are generally two methods of time travel. Skip vs Slide. When you slide through time, you are in essence rewinding or fast forwarding a tape. Time will accelerate to the desired moment. This method, the traveler will witness the rewind and will only allow one of them to exist. When skipping, you are plucking yourself from the time stream and placing yourself in the desired moment. This method, travel is instantaneous and can allow for multiples of the traveler to exist at once. Superman rewound time. He used the slide method and went directly to Lois after doing so. This means those he previously saved...died after his reversal.

Or he could have used the skip method. Like you said, it enables a traveler to pluck themself from the time stream and placing them at the desired moment allowing for two Supermen to be able to prevent both missiles from reaching their destinations.

He couldn't have used the skip method if he rewound time.

Question: Why, in the 3 hour TV version of the movie, does Luthor waste time on that elaborate trap if he already knows, from reading Lois' interview, that bullets, fire, and cold won't stop Superman?

Rob245

Answer: He wanted to see for himself if the stories were true. Some reporters tend to exaggerate the facts and if he had any other weaknesses. He couldn't be sure the kryptonite would work.

While I don't exactly disagree that Lex wanted to see for himself how invincible Superman is, I don't think that's the main reason why he did it. The bullets and fire were simply a charade to make it look like this was his security system. Keep in mind, he wanted Superman to enter his lair because the real trap was the Kryptonite that he had in the lead box.

Question: One thing I don't understand about the movie is why kryptonite is so harmful (almost making him drown in a pool), yet he was born there and he didn't die. Kryptonite did come from his home planet, Krypton, right? How come he didn't die when he was born?

Answer: When Krypton exploded, the resulting debris was chemically altered through nuclear fusion, converting it into kryptonite. Bits traveled through space, some eventually ending up on Earth, where it is now lethal to anyone who was from that planet.

Pieces of Krypton that exploded in the Red Sun were made radioactive, and the Red Sun is one of the weaknesses of the Kryptonians.

I thought the Red Sun was poisonous to Kryptonians and caused the remnants of the planet Krypton to become radioactive and also absorb some of the solar energy from the Red Sun. I was under that impression, maybe I'm mistaken.
