Woah! No sooner did I post about who is playing the villain than the latest news pops up that will make longtime fans VERY happy:
Both Jim Rhodes AND Bethany Cabe will be in the film.
Bethany will of course be Tony's love interest. This has been changed from the previous Millar/Gough draft that had Pepper Potts as the hottie (thank goodness!).
