Ack! Must it involve only actors? I was going for the extremely cheap selection of linking Amelie with Johnny Depp (because he lives in France....geddit? I know, its pathetic from me!

) then onto Orlando Bloom and Pirates of the Caribbean.
I couldn't even dream of linking Kung Pow to it. I just wanted to get one of them out of the way so I could dare someone to connect Braddock 3: Missing In Action to the Rings.
"Now Braddock, you will die."
"Never!"
*massive explosion*
Happy Ending (U-S-A! U-S-A!)
You could, of course, simply link The Lord Of The Rings movies to every other Hollywood blockbuster sort, by virtue of lots of action and simplified relationships.
