It's interesting trying to find an actor who has appeared in more than a handful of major hollywood movies (as opposed to indie flicks in which nobody has really worked with anyone) that has a Bacon Number > 3. I've tried about twenty so far, and everyone is at 2 currently. Even Linda Lovelace and Dev Patel.
There is a counter challenge - Find a living actor who has appeared in three or more major hollywood releases with a Bacon Number of 4 or greater. Define Major Hollywood release as > 100 screens in the United States and more than $1mm in revenue.
