Here's the electric-whip wielding villain of Iron Man 2...

Whoa. Mickey Rourke is looking pretty…what’s the word…oh yeah, CRAZY. Perfect for the role of course, but it has to be said that his tattooed stripped to the waist look is a pretty cool and grungy look. Interestingly, we see the arc technology that forms the basis of Iron Man’s tech powering him. It’s quite a unique approach. While he looks retro in the way Obadiah Stane did (although his King Kong size suit of armour was manifestly less than impressive), Mickey is looking considerably more interesting – and a lot more formidable. He looks like titanium nails, and should be a fitting opponent for the slick Tony Stark (Robert Downey Jr.). Apparently, according to director Jon Favreau, the casting was a no-brainer. I can see why.
