First one to come to my mind is Columbo. Peter Falk knew everyone. And they all wanted to be a villain on his show. He was very good friends with Tony Curtis and Janet Leigh. Tony was never on but Janet was. And their young daughter played the small but memorable role of a waitress. Jamie Lee Curtis.
