Entertainment Tonight has posted a new behind the scenes video for Iron Man 2. In this new video forector Jon Favreau, Robert Downey Jr., Gwyneth Paltrow and Don Cheadle talk about Mickey Rourke’s role in the film as the villain Whiplash. You also get to see Rourke wackin his whips around some more.

I remember when there was a lot of confusion over if the villain was going to be Whiplash or Crimson Dynamo, it kind of became a combination of the two villains. One of the interesting things that they talk about is the fact that once Mickey Rourke was cast they started developing the the character design and costume around him. I think once he jumped on board that’s when they knew what they were going to do.
