Watch the New Iron Man 2 Trailer
Iron Man 2's new action-packed trailer not only gives us a peek at the superhero's latest nemeses (that's Mickey Rourke as Whiplash and Sam Rockwell as Justin Hammer), we also get a glimpse of Scarlett Johansson as the svelte femme fatale Black Widow. The curvy actress endured months of stunt and strength training to look her best in the character's slick Lycra catsuit, and we can't wait to see her kick major butt on the big screen! Gwyneth Paltrow also reprises her role as Robert Downey Jr.'s lady love, Pepper Potts. Click on for a hot shot of Scarlett!
