So much this, creating actor's looks and personality from scratch to fit the demographics is an Hollywood exec wet dream.

Years ago a music studio generated an Asian pop artist. (I can't provide details about it because when I web-search for it I get a hundred results telling me how I can do the same thing myself.)
It's already been done, it's _being _done now, and we're not far away from it being relatively undetectable.

The little secret of AI is that it can't generate shit from scratch. It relies on a large and diverse training dataset in order to make anything at all.
