Guy Pearce and Rebecca Hall on Starring Opposite Tony Stark

The Iron Man 3 stars let us know what it was like working with the special effects and acting alongside Robert Downey Jr. Guy added, "The great thing about Robert is he is certainly able to tow the line between being flippant and pointing out the gravity of the situation. I think a lot of action stars in the past do the flippant stuff and really you don't care about the situation because they don't care about the situation. Where as he brings a certain gravity and the dilemma to the surface as well."
