Marvel likes to publicly discuss their struggles when it comes to locking in stars to their mega-franchises. A lot of folks were worried about Robert Downey Jr. and where he was sitting when it comes to reprising the role of Tony Stark/Iron Man in future Iron Man installments as well as Avengers 2 and 3.
I knew (like most of you) deep down that he’d be back for all of them, because money talks and I’m sure Disney has a lot of money to throw at RDJ if he doesn’t play ball during the first round of contract negotiations.
Now, it’s set in stone. Robert Downey Jr. will for sure be back for Avengers 2 and 3. There’s no talk of Iron Man 4 just yet, but I wouldn’t worry too much until Avengers 2 at least drops.
RDJ is a smart man and while he has expressed interest in branching out his career; he’s also not going to give up on his cash-cow. That would be dumb and stupid for both him and his fans, because he plays the character well and he makes a shit ton of cash while doing so.
