what does he have against the idea of a suit & tie?
is this guy for real?
He doesn't want to be typecast. He plainly feels that playing Clark Kent will restrict the roles available to him once he has moved on.
He simply doesn't want to do anything that will make him look like Christopher Reeve in the Superman movies.
I can understand the Superman suit, however a normal suit that is just crazy, why on earth did he take the role if he is unwilling to actually play the role.
I think Clark wearing a proper suit would be great for show, im fed up with seeing him in his farm clothes (for want of a better phrase).
Should be noted that im sure he didnt think the show would go on this long, and he did not think he would end up playing the Daily Planet Clark, yet alone Superman himself.
