I want to cast Michael Jackson as Gollum, though.

Dunno about that, mg...Gollum still has something of a nose left. And it would be really hard for me to do that to my all-time favorite monster! I can just hear him screaming now:

"Michael Jacksssssssssson!??? Asssssssss me!?
Ssssssssssssshhhhhhhhhhhhheeeeeeeeeit!"
