Are you saying they took a list of actors and said:
''Let's take............................................ him!''
Which actor would be a better pick?
He did a great job in Zodiac, can't say I watched any of the other movies but he's a good actor. They must've had some reason to choose him.
And yes, I think it will sell better with him in it than a less known persian or darker actor.
About the skin color, I'm sorry, I didn't know you had that much feelings about it.
White and persian (tanned? not sure what to call it) people is totally different than black and yellow or yellow and white. That makes no sense.
What I meant to say is that a white person can play someone who's a bit darker.
You don't have to overreact.
