Just before the credits rolled on Iron Man, Tony Stark revealed to the world that he is indeed the armored hero. In the sequel, the filmmakers explore the effects of living in public view by likening the life of a superhero to that of a celebrity. Director Jon Favreau discussed this parallel with the Los Angeles Times:
"Robert had strong points of view on these things. He was propelled quite publicly to a much more successful station and we were able to draw upon that. We were able to comment on the phenomena of celebrity as we know it today."… "It allowed us to draw upon our experiences and certainly Robert’s experiences."
Robert’s experiences? Does that mean that we can expect to see Iron Man blow rails off hookers while wearing a Wonder Woman costume? Seems to me that’s what he’s hinting at. You can quote Favreau on this one you guys. (LA Times)
