Superman Returns so Richard white.....John Jamison?

can someone tell me whats the point of richard white/John jamison in this flick really. Mardsen alsmost missed X:3 to play the John jamison of the superman mythos?Richard wasn't even in the trailer, and not mentioned once in the script reviews. I mean thats just sad, i imagine White will have a few lines then watch supes take his girl [lois] and then recceed into nothing. if your gonna cast a friend of yours in a movie singer, dun cast him as a evoloved extra lime Raimi does. I can't beleive mardsen nearly left X:3 to play the guy who appears with lois a few times.
