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.

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.
Lex Luthor: C'mon, let me hear you say it. Just once. C'mon.
Lois Lane: You're insane.
Lex Luthor: No! Not that! The other thing. C'mon.
Lois Lane: Superman will never-
Lex Luthor: WRONG!
Question: I've always been led to believe that the suit is as impervious as Superman, hence the bullets bouncing off his chest with no marks on the suit. Yet at the end of the movie, the doctors and nurses cut the suit and tear it off of him. Is the suit affected by kryptonite as well?
Answer: There are two stories: a) the suit was made by Martha Kent from the blankets which came with Superman when he was a child and these blankets got superstrenght from the sun too. b) Superman generates an aura which protects him and his suit against such forces. Both stories can be true: either the suit itself is weakend by the kryptonite or Superman's aura was weakend by it. Currently it is said that the blanket-story is the correct one. Also, they don't actually cut it off him - it appears to open along a predefined line (coupled with someone exclaiming "got it!"), presumably the method Superman uses to get into the suit himself.
