Last June, Robert Downey Jr. signed a new two-picture deal with Marvel Studios for Avengers: Age of Ultron, which he is currently shooting, and The Avengers 3, hinting that Iron Man 3 would be the last of his stand alone movies as Tony Stark. During a new interview with Entertainment Weekly, Robert Downey Jr. teased that he may be coming back for Iron Man 4, although it is up to Marvel's Kevin Feige and Ike Perlmutter to make him an offer.

"It's down to Kevin [Feige, Marvel Studios president] and Ike [Perlmutter, CEO of Marvel Entertainment] and Disney to come to us with what the proposal is, and that's on us to agree or disagree. When things are going great, there's a lot of agreement. Right now, this has just been swell, hasn't it? This has been a really good one and it feels good and we're having a good time."

Before Robert Downey Jr. signed his new deal, we reported last May that he wasn't interested in returning as Tony Stark for another stand alone adventure. While it seems that he may have changed his mind, the actor may be getting too pricey for Marvel. A recent Forbes article listed Robert Downey Jr. as the highest-paid actor in the world, earning $75 million last year, most of which came from his back-end deal on last year's Phase Two sequel Iron Man 3. The actor added that he doesn't feel like hanging up Tony Stark's Iron Man suit quite yet.

"It's that thing of: Why give up the belt when it feels like you can barely get jabbed? Most people are saying that right when they get knocked out. The future is, as usual, uncertain."
