Another thing to put on your list is Rohmer's _Perceval_, a very unusual,
beautiful and hard-to-see film--available in the US at least only on
16 mm from New Yorker Films (cost about $250).  I suppose it may be
available in europe on videotape.
ON Excalibur, there is a good article by Chris Shea (Classics, Ball State)
about how the film plays up a certain brand of Christianity in adapting its
main source, Malory.  I'm not sure where it was published.
