Terry Pratchett's Discworld movies (two by SkyOne are live action, two by another company are animated):

The Colour of Magic/The Light Fantastic

The Hogfather

Wyrd Sisters

Soul Music

I've actually been looking for these as well, and even made a thread about it a while back I think, so I'll second this request - surely someone must have them? :)

I have the soundtrack to Soul Music, in M4P format. Unless I find my hard CD, I'll have to convert them to MP3s if you'd prefer.
