I went to Fellowship with one thought in mind "I can't wait to see the House of Tom Bombadil.” It has always been my favorite part of the books. In my mind Tom and the Old Wood set up the whole rest of the story. Words cannot describe how disappointed I was when he wasn’t in the movie at all.
I thought I would share this link, it is one of the best pieces of writing about Tom.
Who is Tom Bombadil?
Also, I just like to share one Bombadil piece of trivia that everybody might not know. If you watch the actor commentary on the extended edition of Fellowship, at the very end Elijah Wood gives a shout-out to Tom, for helping them through the Old Wood. It made me like Elijah Wood even more than I already did.
