Fallout

That makes sense for characters in shows or movies adapted from books or games or existing franchises with established fandoms. My comment pertains to new characters that aren’t established like that, so actors have the job of developing the character themselves rather than conforming to a pre-existing character.

These are very different skillsets for an actor and I would consider it a casting mistake to choose an actor who specializes in one style to play a role meant for the other, and vice versa.
