"He so often gets a bad rap for overacting, but I just don’t see that. When I lived in Brooklyn before moving to California in 1951, I used to go out of my way to watch Bill perform on TV in New York in the early part of his career. And he was fascinating to watch...very theatrical. Great actors, in my estimation, are actors as opposed to reactors. Too many of today’s “stars” are reactors. They can’t really act themselves so they let other character actors around them do the acting and then they react to that performance."
