We all knew that the Iron Man 2 crew had been filming at Edwards Air Force Base in California. This quote from an anonymous source explains what type of scene was shot:
“I worked with Sam Rockwell filming a scene with a combat drone he develops. Sam is a great actor and funny as can be when he's improvising. I hope some of this stuff shows up on the Blu Ray."
Sounds like we will at least get some out takes on the Blu-Ray/DVD release.
