Re: Howard says that not getting to Reprise his Ironman role killed his career!
Neither Howard or Cheadle are really an ideal Rhodey. The character they're playing in the movies is nothing like the comics - either a whiney straight man or a serious straight man to RDJ's mercurial character. They're both stripped of much personality.
I personally would've preferred someone like Blair Underwood who is more typically like Rhodey both in looks and personality. He's probably too tall for RDJ though if they wanted someone around the same height.
