Re: Downey's last?
With Disney's backing, RDJ is going to be in the same position as Johnny Depp over there. He's going to get seriously PAID just to be the face of the Marvel Cinematic Universe.
He may not do anymore solo films but he'll show up in cameos/supporting parts in the rest of the universe and he'll be the highest paid actor of them all.
Bank on it.
