Re: "Iron Man 3" Review and Discussion Thread (spoilers)
Apparently they don't need to worry about RDJ not signing up for a 4th film, since they used a body double and digital replacements in IM3 most of the time anyways.
Well, you still have to pay RDJ for the voice.
Then it's just a question of which is cheaper: paying RDJ to be on-set, or paying the VFX vendors for all that work.
