Re: Titanium Man or Crimson Dynamo?
I voted for Titanium Man; if only for my recollection that traditionally, his armour was always more advanced than CD's - and therefore, more of a viable threat to IM.
Of course, I could be wrong - It's been years since I've read the original stories.
Chiwetel Ejiofor for Black Panther.
Matthew McConaughey for Lex Luthor :( Oh well.
