Re: Downey's last?
Unless Disney/Marvel gives him a small island as payment and gets a time machine, yeah this is RDJ's last movie.
The next Tony is going to have it tough.
Farrel is a good choice btw, one of the actors I wanted before RDJ got cast.
I'm hoping he at least comes back for one more, even if it's him co starring in Avengers 2.
There must always be a Stark in Winterfell
