Other mistake: The spaceship used by Kal El is very small for a 5 year trip - he'd need to eat something in that time too!
Suggested correction: Since we know nothing about Kryptonian technology, we can only speculate how or if supplies are stored.

Directed by: Bryan Singer

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)
Lex Luthor: Gods are selfish beings who fly around in little red capes and don't share their power with mankind.
Trivia: The two writers of the movie make a cameo appearance as the two teens in the museum who are told it's time to leave and they are a bit "man-handled."
Question: If the crystal grows when it is dropped into water, whatever happens to all the chunks that fall off the new continent as Superman lifts it out of the ocean? Wouldn't they simply continue to grow and begin the crisis all over again?
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.
