Urwen has the right reasoning. All well-known chaps with alternative names. You just need to take some of them apart.
I wrote this password partly for the non-Fellowship chaps who rarely get a look-in, and put them in to make it more challenging, but those ones were guessed first, and made the theme tumble at the first hurdle.
Also, let me amend what I said earlier. We sometimes get nearly there with the elements. Especially as some passworders use the style of clue that just gives a flavour or gets you part of the way. I do painstakingly account for every letter in my clues, and this might make me over-sensitive. But I think we should try to get at least part of the way with the reasoning, or get so far and see if another poster can find the rest.
