Oh, and from what I gathered from the movie (and the book, which doesn't mention or even intimate at all that Jason is his son--which is totally weird), Superman took only FIVE years--2½ there, 2½ back--to go to Krypton.
The novelization states he was gone five years, but also Jason is five years old. Uh, he was born 7 months early? (The novelization also mentions the Metropolis River and the City Bridge, when New Troy Island is between the Hobs River and West River and I have no idea which of the many bridges between New Troy and the suburbs is the City Bridge.Abd what self-respecting city would have a bridge named 'City'?)
The film script simply indicates 'a long time'. HOWEVER, the dateline on the Daily Planet article one year after Superman's disappearance is September 2001, which means he left in 2000, which is six years from 2006.
