Granted director and actor Jon Favreau really doesn't have any inside information on a possible Iron Man 4, but he gives his approval that most would love to see Robert Downey Jr. return. Of course we know now that Robert Downey Jr. signed a new contract only to appearing The Avengers 2 & 3 so it seems Iron man 4 may never happen with him. Never-the-less while promoting his new movie Chef the director gives his approval.
If you all may remember Jon Favreau left Iron Man 3 to go make a film that never happened called The Magic Kingdom. Maybe even Favreau wants to return to the Iron Man universe!
