Director Jon Favreau has been opening up quite a bit lately about Iron Man 2, which is currently in post-production. He recently told MTV Splash Page:
"We introduce Scarlett Johansson as Black Widow and she has a dual identity, so that ends up affecting both the superhero side of things and the personal side of things—as I think all good superhero plotlines do."
"Then we have Don Cheadle. We've upped Rhodey's significance in the film and now I think the cat's out of the bag about War Machine, so he's in that suit. How does he become War Machine? What's his relationship to Iron Man?"
"We also have Mickey Rourke and we have Sam Rockwell, two of the best actors of our time. We really have an embarrassment of riches,"
"Now it's up to me as a director to make it all come together, and to also have a light enough touch so that people who just want to go see a fun summer movie will go. I think Iron Man delivered on that. My kids who don't really know the comics and are young were able to go and enjoy the first one and I want to make sure Iron Man is a movie that won't insult grown-ups' intelligence but will also be appropriate for kids."
