People of great character are usually talented,
don't you think? Too bad talent is so often mistaken for character, tho.
Talented in acting? I don't think so.
Nope, complete opposite. With regards to artistic talent, the scale is so heavily weighted towards the absolute flakes that it's not funny. Orson Wells once question if an emotionally healthy man COULD be a great actor. I think Orson was pretty much spot on.
Self-indulgent, inconsistent, neurotic types tend to reach higher rungs on the creative scale than people with character. My guess, and it's purely a guess, is that stable people aren't seeking escape from their tortured lives 24/7 in their imaginations. Artists of all stripes are constantly retreating into their imaginations seeking escape, and that fuels the genius.
