 Favreau had wanted to work with Marvel producer Avi Arad on another film after they both worked on "Daredevil".The director found the opportunity to create a politically ambitious "ultimate spy movie" in "Iron Man", citing inspiration from Tom Clancy, James Bond, and "RoboCop", and compared his approach to an independent film—"[i]f Robert Altman had directed "Superman""—and "Batman Begins".Favreau wanted to make "Iron Man" a story of an adult man literally reinventing himself after discovering the world is far more complex than he originally believed.
