Hollywood superstar Tom Cruise is set to follow-up his role in MISSION: Impossible III with a stint playing the ultimate action star - a superhero. Cruise has already expressed interest in new movie IRON MAN, which would see the diminutive actor transform from a billionaire industrialist to rid the streets of crime in a super-powered suit. But the actor is even keener after hearing US funnyman Jon Favreau is on board. The SWINGERS star has signed to develop and direct the movie, reports PageSix.com.
