Re: Gwyneth Paltrow as Pepper Potts in Iron Man 3
I don't think IM3 is RDJ's true farewell to the character, just an indication his agents will drive up his asking price for a new multi-film contract when the pic opens next year. Marvel Studios will want him for Avengers 2 and Avengers 3... and maybe Iron Man 4?
I think RDJ's willingness to play Tony Stark is similar to Johnny Depp wanting to keep playing Jack Sparrow. And considering RDJ and Gwyneth are BFFs, if he leaves after IM3, then you can kiss her goodbye too. But if he stays on, she'll keep playing Pepper until she gets tired of it.
