Edit your post, osi!

He certainly did the most interesting character in Star Trek. I also enjoyed him in Mission:Impossible (the original TV-series from the '60s, not the Tom Cruise crap) and in the 1978 film The Invasion of the Body Snatchers.
There was also this infamous song
The Ballad of Bilbo Baggins (youtube).
I think that
the song would fit right in the Middle Earth world - as Tolkien made it. There is a whole lot of song in the books, and a lot of humour in those songs.
The video is not a "music video" but from a performance in a TV show which the dancers belong to, so he can't really be blamed for the campy dance...
