Funny, Superman has not only been stripped of his Americanism, but he's also lost his intelligence. He speaks like he's on MTV. "Truth, justice, and all that stuff". I guess we'll have to go back and rent the Christopher Reeve version.
Uh, Superman didn't say that in the movie, Perry White did and it was in the middle of an exhortation to cover Superman to the detriment of covering Lex Luthor's plan. This is what happens when people who don't see something make comments on it.
