Director Shane Black takes a more 'grounded' approach to the story
"[Marvel] allowed for a different, sort of stand-alone film, where we got to be more character centric and look basically back to basics at what Tony Stark would do next - what was left to tell of his story," said Black. "And that was very appealing to me. So to make it more of a thriller and to make it more about Tony and less other-worldly, and sort of just ground it more - that was our intention. I hope we succeeded."
