Jon Favreau has come quite a way since his days hanging out with Swingers and Iron Man is easily his biggest project yet. Yahoo! Movies has a clip of the director on the set of superhero saga. Iron Man kicks off Summer '08 when it opens May 2nd and expectations are high. The film stars Robert Downey Jr. in the title role, along with Jeff Bridges, Gwyneth Paltrow and Terrence Howard. If returns are good, then another superhero franchise could be born.
