"Six degrees of Kevin Bacon" is played by linking actors through a string of common movies. For instance, Katherine Hepburn can be connected to Kevin Bacon in three steps:
1. Katherine Hepburn was in
On Golden Pond with Jane Fonda
2. Jane Fonda was in
The China Syndrome with Jack Lemmon
3. Jack Lemmon was in
JFK with Kevin Bacon
The real challenge is to connect an actor who made a few films in the 1930s or 1940s to Kevin Bacon. I managed to connect
Butterfly McQueen (Prissy in
Gone With the Wind) to Kevin Bacon in six steps, but it wasn't easy.
