I disagree with Ahnold and Vin. These are bad actors who knew their limitations and chose roles which did not force them to be good actors. The fact that they did not take themselves too seriously puts them in a different category than your hall of shame.
I agree with you re: Arnold and Vin. They never have made a pretense of being great actors. Neither would consider themselves artists or talk about “the craft” of acting. They found a lucrative niche and enjoyed making lots of money. Good for them.
