“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,” Downey said. “When things are going great, there’s a lot of agreement.” …
Until his bosses decide he’s too rich for their blood, Downey says he’s happy to hold on to the iron mask. “It’s that thing of: why give up the belt when it feels like you can barely get jabbed?” he says — then adds a caveat. “Most people are saying that right when they get knocked out.”
He shrugs, and until Marvel says otherwise, Downey leaves us with points of ellipses and a grin: “The future is, as usual, uncertain.”"
"When EW visited the set of Avengers: Age of Ultron, we asked Downey point-blank: Does he want to star in an Iron Man 4?
His answer wasn’t so point-blank. In fact, he starts to sound a little like a Magic 8-Ball as he tries to keep it vague. But the answer we gleaned was: Signs point to yes.”
