Re: Downey's last?
I think Robert Downey Jr IS the cinematic Tony Stark, the same way that Harrison Ford IS Indiana Jones or Bruce Willis IS John McClane. And to me, getting a new actor to play Stark - be it for a sequel or a reboot - would be like getting a new actor to play Jones or McClane: yes, they COULD do it, and eventually they probably WILL do it, but that doesn't make it any less stupid. It just won't be the same.
