Ethel Merman was in It's A Mad Mad Mad Mad World with Terry Thomas who was in 12 + 1 with TBT.

I nominate Bette Davis.

Sandra Dickinson? funny You shouid mention that, saw a preview of the Hitch hikers guide to the galaxy this morning.
Easy peasy.
She was in the telly version of the above as Was Peter Davison. He was not in the Goodies as stated erroniously in the book by Robert Wassismush, but was in the 5 Doctors with jon Pertwee who was in Wacky Wales, an episode of the Goodies.

Ethel Merman is my next choice!

Christopher Reeve was in "Village of the Damned"
with Linda Kozlowski who was in "Crocodile Dundee" with Paul Hogan
who appeared in "Paul Hogan's England" with Tim Brooke-Taylor!

Almost too easy.

How about Sandra Dickinson

Kylie Minogue was in "Moulin Rouge" with Ewan Mcgregor...
...who was in "Star Wars:Attack of the Clones" with Christopher Lee...
...was was in "Around the World in 80 Days" with Eric Idle...
...who was in "At Last the 1948 Show" with TBT!

I could have done it quicker, but I wanted to avoid the CLEESE!!!

Next, Christopher Reeve.

I knew it would come down to Kevin Bacon one day, seeing as he was the actor that the original game was basec on. Anyway, getting on with it.

Kevin Bacon was in "Sleepers" with Vittorio Gassman...
...who did "12 + 1" with TBT.

Next, Kylie Minogue (she HAS done a few movies, albeit entirely forgettable ones - with the exception of Sample People, which was actually a great flick...anyway, yes, Kylie it is.)

Waaaaay too easy

Christopher Eccelston was in Gone in Sixty Seconds...
with vinnie jones (plays the sphinx)...
who was a guest on The Frank Skinner Show...
so was michael palin whom was in broaden your mind (and various other things both cleese and non cleese related) with TBT!!!

try someone not from the same movie

how about Kevin Bacon

Nicholas Cage was in Gone in Sixty Seconds...
with vinnie jones (plays the sphinx)...
who was a guest on The Frank Skinner Show...
so was michael palin whom was in broaden your mind (and various other things both cleese and non cleese related) with TBT!!!

Now lets see...dr who is on in 15 mins, so lets try christopher eccleston

I'll try this one

Lorne Green was in "Conquest of the Earth" with ...
Wolfman Jack, who guested in "Married With Children" as did  William Oddie (O.B.E.) ... who appeared with TBT in some show I can't think of offhand.....

lets try Nicholas Cage

One toy boy to another....
Scott Wolf was in Double Dragon with Robert Patrick. He was in Terminator 2 with Arnie who was in Junior with Emma Thompson. She was  in Peter's Friends with Stephen Fry who has done several episodes of ISIHAC with the lovely Timothy.
Roghto who next.......
Lorne Greene

Cillian Murphy has just completed filming "Batman Begins" with Tom Wilkinson...
...who was in "The Importance of Being Earnest" with Rupert Everett...
...who did a brilliant performance in "Another Country" with Cary Elwes...
...who was in "The Princess Bride" with Peter Cook...
...who appeared in "An Evening at the Court" with TBT.

Phew! I managed to avoid the obvious CLEEESE! link. That should be a new challenge, finding a link that completely dodges all things Cleese!

Next in line...does anyone remember Scott Wolf? Let's see if TBT can be linked with a toy-boy.
