IRON MAN (2008)
Tony Stark/Iron Man
Downey headlines the first big release of summer 2008 as Tony Stark, the billionaire businessman who invents a tricked-out, super-powered suit to fight evildoers. Fans of the original comic book applauded the movie's producers for casting Downey, who shared the character's history of substance abuse (though this element isn't mentioned in the film).
