Fact From the Vapor of Nuance
If you've been seeing a lot of news stories lately where Robert Downey, Jr. casually says something to the effect of "I'm not going to be playing Iron Man forever" or "yeah, I'd be interested in seeing who else could be Tony Stark," it might be informative for you to remember that his contract actually is up to be renegotiated in this post Iron Man 3
era. These seemingly casual remarks are actually the first salvos in the epic game of moneyball that's about to be played between Downey and Marvel Entertainment over what he'll be paid to appear in The Avengers 2
and possibly The Avengers 3
This means that some news outlets are pulling out all their unnamed sources to talk some straight insider talk about the contract negotiations between Downey, all of his Avengers co-stars, and Marvel. So you should take this with a grain of salt, but one of those news outlets is claiming that Marvel is mulling over script ideas for some pretty exciting secondary characters.
