Xoanon here,

It's with great excitement that I announce that the voice for Gollum has been cast!

Another email spy has been in contact with the Victoria Burrows' casting office and has garnered this tantilizing piece of info.

a) The voice actor is "Name" talent (i.e., they're going to use his name to
help market the film because he's a very well known actor).

b) The Producers (Peter Jackson, et al.) are very happy they got the "Name"
they wanted.

ah ha! Well, at least this gives us something more to talk about than Sean Connery.
