“These three images I did at the very end of production as alternate suit designs that would have been in a Hall of Armor coda at the end of the film,” writes Saunders. “I spent a lot of time on developing this [War Machine] suit, which was of course cut from the script about half way through pre-production. Originally it was going to be called the MK IV armor and would have been weaponized swap-out parts that would be worn over the original MK III armor. Earlier versions were red and gold, and would have been worn by Tony Stark in the final battle sequence.”
But before you get too excited, Saunders warns that “if there is a War Machine in [Iron Man 2], it’s unlikely to be this one.”
