Speaking at Comic Con's Iron Man panel--at least in some sense answering the question, "Is there any way to get Gwyneth Paltrow in an outfit more farcical than her $90 goop t-shirt?"--Jon Favreau and Marvel production president Kevin Feige let slip their apparently long-held interest in getting Paltrow's Pepper Potts in an Iron Man suit.
In the comics, Potts eventually gets her own For Her edition of Tony Stark's armor, and it seems the film Potts nearly has, too, with Feige reportedly saying (via), "Everyone at this table thinks it would be the coolest thing in the world to see Pepper get in the suit at some point."
"We almost did it a few times; we talked about it a lot. I think we all share your enthusiasm for that, and we all want to see Gwyneth kick a little ass," Favreau added, mistakenly thinking Comic Con attendees are just nerdier Chris Martins.
Given their word choice and the fact they were willing to talk about it at all, it doesn't sound like Tony Stark's unnervingly-hollow-voiced assistant will be suiting up for the third Iron Man, but then again, reports denied Ben Kingsley would playing Mandarin before Marvel turned around and confirmed it last weekend, so you never know. Maybe we'll yet see Gwyneth Paltrow with a layer of metal covering her affectations. If not, well, then I guess we'll just see her in some $200 jeans.
