I'm sure I saw a version of this that had Rod Steiger at #1, via a very long career as a mostly supporting actor.
It looks like it's very sensitive to the choice of dataset, so I guess there's no one "correct" answer.
Both this new one and the Oracle of Bacon seem a little suspiciously weighted towards living actors, which makes me think their data is skewed towards modern movies. But Hollywood has been around for a long time, so if there were a correct answer I would have thought it would be likely to be somebody very old or dead.
