There had been some speculation for a while that Robert Downey Jr. might not return to the iconic role of Tony Stark, aka Iron Man, after the third film in the franchise and the massive paychecks Marvel has had to write for the guy, but it’s now been confirmed that RDJ will be stepping back into the role for the next two Avengers flicks. Joss Whedon had gone on record to state that he wouldn’t make an Avengers 2 without RDJ as Tony Stark, so I guess that’s taken care of. Yay.
Currently, there are no plans for a fourth Iron Man film, but given the huge success of the first three installments and the importance of the character in Marvel’s Cinematic Universe, I would be very surprised if we didn’t see more Iron Man before the third Avengers.
