OK, I can do Amelie and To Kill A Mockingbird with only one intervening film in each:
Amelie -> Mathieu Kassovitz -> The Fifth Element -> Ian Holm -> LotR
To Kill A Mockingbird -> Robert Duvall -> Deep Impact -> Elijah Wood -> LotR
But can anyone do Jules et Jim in less than this:
Jules et Jim -> Francois Truffaut -> Close Encounters of the Third Kind -> Steven Spielberg -> Raiders of the Lost Ark -> John Rhys-Davies -> LotR?
Ah, IMDb is a wonderful thing.
