Six Degrees of Kevin Bacon

Well this one kinda seems to require research.


Klaus was in Firefox with Clint Eastwood.
Eastwood was in Unforgiven with Morgan Freeman
Morgan Freeman was in Batman Begins with Liam Neeson
Neeson was in Michael Collins with Jonathan Rhys Meyers.

Alessandro Juliani and Giulietta Masina

Quite do-able, obviously!

Alessandro Juliani ...was in Watchmen with Jackie Earle Haley
Jackie Earle Haley was in The Day of the Locust with Donald Sutherland
Donald Sutherland was in The Great Train Robbery (1978) with Sean Connery
Sean Connery was in Murder on the Orient Express (1974) with Ingrid Bergman
Ingrid Bergman was in Europa '51 with... Giulietta Masina.

I wasn't sure about that one, because Alessandro Juliani is primarily known for TV and voiceover work, not feature films, but I found something! (He was the Rockefeller Military Base Technician in Watchmen.)

Anyway, here's my next one...

Romolo Valli and Jamie Campbell Bower
