Jon Favreau commented on the location in his tweets — here is a little confirmation from the base that Iron Man 2 filmed here, along with some pictures:
Scenes from the upcoming movie Ironman II were filmed here May 11 through 13, with the support of about 60 members of Team Edwards taking part as extras and technical advisors.
The director, Jon Favreau said he was excited to return to Edwards for the sequel for the landscape, but not for the way it looks but for the history it possesses and the professional Airmen and Marines here.
“All these real military assets make the movie more authentic and the topography and the beauty of the Desert and flightline open the movie up,” he said. “But it’s the rich history of the location and the deep roots it has with flight that gives Tony Stark and his father a pedigree in the aerospace industry.”
