ET Premieres Behind-the-Scenes Footage from Iron Man 2

Entertainment Tonight has posted a 5 minute feature on their visit to the set of Iron Man 2, which features a mix of cast interviews with Robert Downey Jr. and Jon Favreau, and a lot of behind the scenes footage.

Robert Downey Jr explains how and why Tony Stark first meets Whiplash (Mickey Rourke) on a race track, while Scarlett and Gwyneth vaguely discuss the love triangle. We see a couple explosions and a bunch of Whiplash-generated destruction.
