It took a while for me to resolve the conflict between who he is and the great detective he plays on TV.
I slowly realized that a good actor creates a person different than themselves. The actor himself may be a disgusting human being, but he has created an imaginary person who by the magic of theater allows me to enjoy the creation.
That is a pretty wonderful quality of the theatrical world. It is fortunate because the theatrical world is filled with disgusting, stupid and offensive actors.
