Anything having to do with The Lord of the Rings!
Apart from that would be: Reading, Writing, Music (listening and playing piano, some LOTR pieces of course) making movies, acting
Favorite Tolkien character:
If I have to narrow it down to just one I'd have to pick Frodo Baggins.
He's one of the most self sacrificing characters of literature. After all that he has to go through to destroy the Ring he still cannot go on living peacefully in his beloved Shire.
