I voted Yes, I think we can all agree, that his his talent is limitless, he wasn't on my list, simply because I never thought of him, it took me by surprise as it did many who have posted, but after giving it thought, I like the casting.
The problems I have are simply, can he keep himself straight, personally, I truely believe, he is one of Hollywoods most talented actors, but his personal life has derailed many comebacks.
Second, can he pull off being a superhero, he will need to do stunt work and action scene's.
Other than that, Robert is a very good choice and one I will support.
