Well, there's always James Eugene Carrey.
Shave him down and he could play Gollum... Then again, Gollum would be running around frantically waving his arms and YELLING "my precious, my preCIOOOOUUUUUS!" (capital letters at a higher pitched voice) instead of slinking about with a whisper...
I am looking forward to the 2 upcoming flicks, but I will say that without ever reading the books (I almosted did in middle school), when Gandalf lists off the dwarf's names, it seems a bit goofy to the uninitiated....
