This is a game, whose title is a
Mondegreen of
Six Degrees of Separation, in which it is said that any individual can be linked through his or her film roles to actor
Kevin Bacon within six steps. For example,
George Clooney was in
Ocean's Eleven with
Matt Damon, Matt Damon was in
The Departed with
Jack Nicholson, and Jack Nicholson was in
A Few Good Men with Kevin Bacon. It should be noted that this spreads across all actors;
Megumi Hayashibara can be linked to Kevin in only two moves
* She was in
Vampire Hunter D: Bloodlust, which included Micheal McShane in the dub. He was in
Balto with Kevin Bacon
. It's often a game for film nerds to test the abilities of each other.
There is a whole website, The Oracle of Bacon, dedicated to this found
here.
Mathematicians have extrapolated this phenomenon and given it a name: "Bacon Number", which sounds like one of those impossibly high numbers with dangerous implications for the
future of the universe but is in fact incredibly low. Researchers have demonstrated (
true story!) that almost everyone has a Bacon Number < 10, due to Kevin Bacon appearing in, mathematically speaking,
almost every film on the planet. For instance,
Kevin Bacon himself has a Bacon Number of 0. Chew on
that,
Mr T! (The Oracle of Bacon claims that three persons on the
IMDb have Bacon Numbers of 9, the highest listed, but does not say who they are.)
Curiously, the most connected person in acting is not
Kevin Bacon. Research by people who found it important enough to do so discovered that the centre of the Hollywood universe shifts over time, and currently rests with the late Dennis Hopper, followed by
Harvey Keitel and Donald Sutherland.
Mathematicians (and all scientists) also have a similar ranking called the Erdős Number, based on co-authorship of mathematical articles with deceased mathematician Paul Erdős. Inevitably there's a combination, the Erdős-Bacon number, based on adding the two together. Thanks to the documentaries, and occasional extra work on math-related films, some mathematicians have EB numbers as low as 3. More surprising are actors who attack the problem from the other side. Danica McKellar (Winnie from
The Wonder Years and bona-fide mathematician) and
Natalie Portman (wrote a psychology paper at Harvard with an Erdős link) each have Erdős-Bacon numbers of 6. (This ties them with
Richard Feynman.)
There is also now the Sabbath Number, based on how many collaborations it takes to get from a given musician to
Black Sabbath. And, of course, musicians who've appeared in films have Sabbath-Bacon numbers, and a surprising number of math-geeks turned musos have Sabbath-Erdős numbers. And then there's the Sabbath-Bacon-Erdős number. The only person known to have a single-figure Sabbath-Bacon-Erdős number is physicist,
The Simpsons guest star, and
Pink Floyd guest vocalist
Stephen Hawking.
