Somehow it's a fun fact that you can reach any other actor in four moves, but a much less fun fact that you can probably-reach any other actor in 2.6 moves. "Connectedness", huh. Though it was interesting to see that Frank Welker used to be in fourth place. Never heard of him. Or I've only heard of him, he's a voice actor. He does cartoon animals, often without lines, lots of miaowing.
