If the key to casting Superman is casting Clark Kent as the poster suggests, then all the Routh haters should get their arses out of their heads because Brandon Routh personified Clark Kent to a tee.
Also Tom Welling is well known to whom? Smallville fans? Superman fans? Cheaper by the Dozen fans? I bring this up only because I seriously doubt that Welling is well known as Christopher claims he is. Most of my friends don't know who he is but know that I watch Smallville.
By the way I think Joe or Armie Hammer would be a good choice for Superman but for some reason I think they're gonna go for a total unknown and none of those on that list will be Superman.
