Just after the awesome movie Iron Man was released ,it was or is the rumor that Robert Downey Jr. ,the actor of Iron Man 1 and Iron Man 2, has turned down the proposal of Marvel Studios for his portrayal as tony Stark in the expected movie Iron Man 4 . Which still seems rumor to me.
I saw the movie Iron Man again .In the movie now Tony Stark is in serious relationship with Pepper Potts .
The only possibility that comes in my mind is there son!!!
Why don't you tell me about you reviews about who is going to carry on the legacy of Tony Stark in comment and who do you think is going to play the character for his son???
