Shane Black described his take on the film as not being "two men in iron suits fighting each other," and more like a "Tom Clancy thriller", with Iron Man fighting real-world type villains. Drew Pearce added that they would avoid magic and space, with Iron Man 3 being "a techno-thriller set in a more real world than even The Avengers". The duo spent some time discussing themes and images and ideas before starting the script. While writing, the focus was to avoid scenes of pure exposition, making every moment propel other narrative points forward. Some elements from the comics were used even if in different connotations, such as making Rhodes wear Norman Osborn's Iron Patriot armor and naming some characters with names from unrelated people in the Marvel Universe, such as Eric Savin and Jack Taggart.
