I had the great good fortune to write the cover story for the May issue of American Cinematographer magazine, detailing the terrific visuals of Iron Man 2, and I had a wonderful time doing it. (And yes, I was proud indeed when I was able to title the piece "Armor Wars.") While reporting the story, I visited the production on location at Los Angeles' Sepulveda Dam (which stood in for the exterior of Stark Expo), and I received a wealth of great information from everyone I spoke with, including cinematographer Matty Libatique, ASC; 2nd-unit director/cinematographer Jonathan Taylor, ASC; visual-effects supervisor Janek Sirrs; gaffer Mike Bauman; and director Jon "Happy Hogan" Favreau. The full story--including a sidebar focused on the 2nd unit's incredible contributions--can now be read online here, at the American Cinematographer website, where we've also posted an even bigger selection of photos than we were able to fit into the print edition. Enjoy.
