Try foreign and old actors, e.g. Mazzaropi (famous Brazilian comedian from the 1950'-70's), Google computes a bacon number 5... but The Oracle of Bacon returns 3, they have a bigger database.
I got to 3 with Bela Lugosi. I couldn't get any further, so I finally turned to the comments to see who had >3.
Me too. I had to go to foreign child actors. Found a 4 with Kåre Hedebrant who played the kid, Oscar, in "Let the Right One In" (The original swedish version of Let Me In)
Edit: However, oracle of bacon says he's only a 3...
The first one I found was 3: Chip Foose, a car designer. I couldn't think of anyone and he happened to be smiling at me from the calendar on my desk.
