Re: Is Robert Downey Jr. a good choice?
I've seen alot of Downey's work and he's certainly a talented actor. But I see him working as Stark.
If they were going in this age and acting style range, I think Val Kilmer would have been a better choice, although he might have passed, simply because he's already played a billionaire superhero.
As for the Mandarin they'd better not go young. They need to hire an acting vet out of Hong Kong, if not an Asian-American actor with solid experience (Maybe Tony Liu, Tsi Ma or John Lone).
