if you had to choose an actor to play the darkling, who do you think would best fit the part? regarding looks and acting?

This question is impossible for me. But I will say this… I think acting chops and charisma are more important than a checklist of physical descriptors. Yes, the Darkling is supposed to have black hair and gray eyes and, y’know, be with the hotness, but it’s a lot more important that you believe he can conquer worlds without breaking a sweat.
