Yeah, but will they use Ozzy's song on the soundtrack?

Remember that 70's rocker "Ironman" by Black Sabbath? Somehow still think of that song when I think of the comic book character. Looks like the movie version of the classic Marvel character, as well as Captain America, are in the pipeline. Looking forward to them. Who would you cast as Ironman? Or Captain America? I guess there have been rumors of Dominic Purcell being cast in the new Hulk movie, but I'd rather see him as Ironman. Give Eric Bana a second go-around at the Hulk! And Nathan Fillion would be a natural as Capt. America don't you think?
