I'm going for "YES".
As I said earlier, Downey is a fantastic actor. He's got serious gravitas and will bring credibility to this role for the mainstream audience. So I have no fears regarding his acting ability; he's got chops.
But I guess I am slightly concerned with his physical aesthetics. Stark is a handsome, rich playboy that every woman wants a piece of. Not saying that Robert isn't a good-looking guy, but he isn't that
kind of good-looking. But I will say however, that with a stache and goatee Robert does have a striking resemblance to the character.
Overall I am very confident with the choice, with just a slight reservation.
You're obviously a idiotic troll looking for attention.
Now please...go to the top of the highest staircase you can find, and just fall.
Don't question it...it's for your own good.
Once you've fallen, just lay there. As you lay, simply think of how stupid you are and how your stupidity got you there.
