Hmmm... this sounds fun. But I'm not sure whom I should try out for....Maybe Gandalf, or better yet, the Balrog!!
No, it's either Gandalf, Eomer or Faramir for me.
But, if I may make a suggestion. Considering that a lot of people will not have time or patience to do this, why not make a reanactment of it in an RPG form? I'm not exactly sure how it would work out, but it could if we really tried.
