There is a parlor game that people with enough movie trivia knowledge can play called "Six Degrees of Kevin Bacon" it's premise is that any individual can be linked through his or her film roles to actor Kevin Bacon within six steps. If you picked John Wayne, then you would say "John Wayne was in How the West was Won with Eli Wallach and Eli Wallach was in Mystic River with Kevin Bacon" so John Wayne is within 2 degrees or has Bacon number of 2. That's if you knew that. If you don't know how many degrees any particular actor is within Kevin Bacon, then just go to oracleofbacon.com and yes, type in any actor and it will compute everything for you and link any actor to him, including the movie titles. This website is a trip.
