MSNBC reviews the many (possible) faces of Superman.
My pick, Jude Law, is among the candidates.

CBSNews also looks at this particular issue.

While I'm talking about Superman, I saw a bumper stiker the other day that said WWSD?
Except, the "S" was Superman's emblem. It was pretty rad.
If anyone knows where I can get one of these, please let me know!
