Yes, it was very well done on th beeb.
Interestingly, Tokein and CS Lewis were both members of a Cambridge club which they called the Inklings IIRC. Lewis wrote some very strange adult books about astral viewing, ie projecting your conciousness elsewhere, including on other planets. That Hideous Strength or something - very bizarre.
Also, if anyone is into these sort of books, The Dark is Rising series by Susan Cooper is excellent, and apparently there is this Phillip Pullman with His Dark Materials series which is meant to be very good - also a forthcoming film.
The susan cooper books are set in Cornawall and have Uncle Merlin & holy grails, stone circles etc...very nicely done & atmospheric.
