Oh, yes! I love Brian Sibley's adaptation for BBC too. I love the voices of Merry and Pippin, and of course Ian Holm's Frodo, and Bill Nighy's Sam. Aragorn and Arwen is a bit of a disappointment, and so's Gollum. I can't help comparing him to Andy Serkis's portrayal of him. But Gandalf is amazing. I love the way Sibley incorporate the little details from the book and the songs sound so folksong-ish.

Did you see Bill Nighy in Blow Dry (opposite Alan Rickman)? British actors never cease to amaze me.
