A fourth Iron Man film may be unlikely to happen, but that doesn't mean we've yet seen the last of Tony Stark. According to The Hollywood Reporter, star Robert Downey Jr. has officially signed on to appear in both Marvel's upcoming films, The Avengers 2 and The Avengers 3.

Though this is great news, it is slightly surprising: Downey Jr. hasn't held back from revealing how much he made off of The Avengers ($50 million, for the record), and his contract with Marvel was up after production ended on Iron Man 3. It was speculated that, as he was much more expensive now than he was when the company first signed him, no contracts would be re-negotiated.

Recently, however, Avengers helmer Joss Whedon pretty much stated that the film wouldn't be made without Downey"I have no intention of making Avengers 2 without him, nor do I think I’ll be called upon to do that. I don’t think it’s in my interest, Marvel’s interest, or his interest, and I think everything will be fine," he saidso that likely had something to do with it.

The Avengers 2 is slated to begin production in March 2014 for a May 1, 2015 premiere.
