Mickey Rourke & Scarlett Johansson in Iron Man 2

The amount of talent Marvel has assembled for Iron Man 2 is pretty impressive. You have actor/writer Justin Theroux penning the script, multihyphenate Jon Favreau behind the camera, and A-list talent like Robert Downey Jr., Gwyneth Paltrow, and Samuel L. Jackson reprising their roles from the stupendously awesome original (with Don Cheadle stepping in for Terrence Howard, to boot). Then, then, you add Sam Rockwell and Mickey Rourke as villains and you have the formula for one hell of a sequel. And let's be serious: Rourke was born to play a villain in a superhero flick. Just look at that face! It was meant to be.
