Is this the scene where they were considering some shots of Elijah made up to resemble a Gollum-like creature?

I just mentioned that to Mews. Yes, there was such a version of the scene planned. There are still of EW in the gruesome "Gollum-Frodo" make-up, and there's a clip of him wearing the makeup on set, maybe even acting, in the DVD extras. I am so glad they didn't go with that. The spectacle of Frodo as "un-hobbited" as he already appeared in this scene is *more* than enough for me. :)
