Robert Downey, Jr.: 'Iron Man 4' A Possibility in the Future?

Robert Downey, Jr. laughs with some crew members on the set of a commercial shoot on Sunday (May 19) in Miami, Fla.

The 48-year-old actor wore a variety of different outfits while shooting on a boat with crazy looking creatures!

“I’d go start another one tomorrow, but it’s not tomorrow,” Robert recently told EW about the possibility of Iron Man 4. “And there are a lot of other considerations. But I also don’t like the idea of leaving people hanging or leaving people in the lurch.”

“My intent is to launch another franchise, independent of any that I can even imagine right now,” Robert added. “My intent is to dominate the playing field for as long as I can, with my own challenges, with myself.”
