Thanks for the link.
I know nothing of his acting but have it grow some facial hair and grow his hair out a bit and he might look pretty good. Although I feel like he is kind of small for the role.
That was my impression too. His super blue eyes do have a Christ-like "Greateset Story Ever Told" look. But he is so young and skinny.
When I saw his picture in that link those were my first thoughts too. Hopefully he'll do a good/great job as the character.
