I was lucky enough to score a backstage wristband from secret sources deep inside of Comic-Con, and while we wait for the Marvel panel to begin, I took a turn backstage and noticed a surprise guest: Gwyneth Paltrow! She wasn't listed as being here, but she'll be out front in moments, and looking pretty darn stunning in a gauzy little red dress. Hopefully she'll let us know how big of a role Pepper Potts will be playing in the Iron Man film.
