Billionaire playboy Tony Stark (Robert Downey Jr.) and his high-tech armor suit are faced with a new super-powered enemy (Mickey Rourke) and a mysterious but hot new personal assistant (Scarlett Johnannson) in the blockbuster comic book sequel Iron Man 2 (2010). Scarlett and Gwynneth Paltrow (who returns as Iron Man's girlfriend Pepper Potts) keep their clothes on, but we do get to see Scarjo's bra as she changes into her skintight leather suit in the back of a limo and that will turn you into an iron man.
