In an interview with The Daily Beast, filmmaker Joss Whedon said he does not intend to make the much anticipated Avengers sequel without the original Iron Man, Robert Downey Jr. As Whedon puts it,
He is Iron Man. He is Iron Man in the way that Sean Connery was James Bond. I have no intention of making Avengers 2 without him, nor do I think I’ll be called upon to do that. I don’t think it’s in my interest, Marvel’s interest, or his interest, and I think everything will be fine. But I know that this is Hollywood and you roll with things. You have to be ready for the unexpected. But I loved working with Robert, and everybody knows he embodied that role in a way no one else can.
Would you see the Avengers sequel without the infamous Tony Stark?
Nope. But I do think it'll be the last time RDJ dons the suit.
