If we gonna have an actor with a French name, why not go with Garpard Ulliel? I think he has a better look for the character
I don't think the actor's name matters, as long as he speaks perfect English. I suggested Arnaud because I had recently been watching
The Borgias, and I was really impressed with him there. I agree that the actor chosen should bear resemblance to the original character, but being young, dark-haired, light-eyed and handsome, I thought him to resemble Dick enough.
Of course, there are other people who look more like comic-book Dick Grayson (Brant Daugherty, for example, looks like he jumped right off the page), but I had to take acting abilities into account. That is the most important part, after all.
This is not to say that Gaspard Ulliel can't be a competent actor or choice for the character. I'm just unable to comment on him as I've never seen anything he's been on. Is he any good?
Alden Ehrenreich - Dick Grayson
You know, I've never actually seen Ehrenreich act (hopefully that'll change with me watching
Hail, Caesar! this weekend), but I've heard a lot of good things about him in the past. What have you seen him in?
