I understand what you are saying.. but like I said, your view is skewed by your environment, and what you consider “normal”.
If a Korean or Indian film maker where doing shakespere they would use Korean or Indian actors usually.
The same way Hollywood used white men in makeup to play Indians or Asians in old movies.
I have been watching a lot of Bollywood and Korean-made films recently and it what I am trying to explain suddenly accured to me.
