Sorry it took so long... I started this back in August!
Okay, here's the list... Over 120 actors (and a few directors acting), all linked Kevin-Bacon-style!
The names of actors and movies link to IMDB's credits and cast respectively. No pictures, as this would just clutter everything. Click the link, or do a Google or Wikipedia search.
Bold names denote Oscar winners or nominees. Actors for main or supporting, movies for best picture or nominees.
[The list is not chronological... I started with Bill Pullman and worked outwards. So if it seems that I'm avoiding certain obvious links, it's because they were used elsewhere. Don't worry... your favorites will appear. If not, mention my omission in the comments, and I'll try to work them in later.]
Paul L. Smith
Tommy Kirk [A member of the Disney bRat Pack, plays a Martian in...]
Anthony Michael Hall
Michael Caine [a proto-Kevin Bacon]
Kurt Russell [Another Rat Packer]
Bryan Singer [No. Really.]
Joanna Lumley [Check out THIS.]
Dick Van Patten
Charlton Heston (Only nominated once, but won for Ben-Hur)
[Oh, crap... got Roddy McDowall confused with Malcolm McDowell!]
[Man... it took some work, but I got it done!]
Helen Mirren [Also a Dame Commander of the Order of the British Empire]
Jeff Goldblum [The first multiple link between actors.]
Samuel L. Jackson
Tommy Lee Jones
Jerry Lewis [My favorite link on this entire list. Wish I could have linked Valerie Harper.]
James Brolin [also in Fantastic Voyage]
Majel Barrett [She rivals Leonard Nimoy and Mark Lenard for the most variations of Star Trek.]
[Crap... had a direct link to Anjelica Huston, but it doesn't exist. Took some work... but here's the patch.]
Richard Pryor [You could take a shortcut and use Carol Kane to link to Ms. Huston. Here's the scenic route:]
Michael Jackson [Yup, can link to Ms. Huston via Captain EO... patience.]
Robbie the Robot [He plays himself in Forbidden Planet, but since this is a fictional movie, not a documentary, and a major role, it counts.]
Chuck Jones [Yes! My second favorite link on this list.]
Johnny Depp [Betcha you thought I forgot him, didn'tcha?]
And thus ends the initial list. Why end it at Harrison Ford? Because once I got going, and found it approaching 122 names, I decided to link all of the Batman movies. Luckily, I was able to splice in the last Batman movie (actually the first) via Kurt Russell, although I had to sacrifice a double (Kurt Russell + John Carpenter = The Thing + Escape From New York) as well as Jamie Lee Curtis (EFNY/Buckaroo Banzai) and John Lithgow (Banzai/Twilight Zone). Actually, it would be slick to link Buckaroo Banzai and its sequel, Big Trouble in Little China via Kurt Russell and Jamie Lee Curtis.
Any corrections, comments, suggestions, criticisms... let me know.
