For everyone who's seen the new Superman movie, I need some help with what may be a plot hole. For those who don't want the movie spoiled, consider yourself warned.
OK, so Luthor goes to the fortress and hears Brando tell Kal-El that by the time he "hears this" Brando will have been dead for thousands of years. Yet we're then supposed to believe Supes makes the round trip to Krypton in five years??? Maybe I'm missing something here, but did Singer, et al royally screw up here?
