Iron Man 4 Anyone?

Iron Man 3 made Marvel over $1 billion worldwide, yet the studio seems to be in no hurry to get moving on a fourth film in the series.

Robert Downey Jr. wrapped work on Joss Whedon's superhero team up sequel "The Avengers: Age of Ultron"" and is only committed to doing one more Marvel film which is the third "Avengers" movie.

While attending Toronto International Film Festival this week,RDJ. confirms to Variety there are still no plans for another "Iron Man" flick saying "There isn't one in the pipe. No, there's no plan for a fourth 'Iron Man'."

He was also asked if he'd "let" anyone take over the role: "I like that the idea is that it would be up to me, like I'm casting director for Marvel."
