Cheers Witchy,
you have a good point, I did consider making Gollum as a hybrid Gollum - Bruce Lee, but thought that would just look too weird. Instead I'm opting for giving him those scars across his chest from the dragon movie. Personally I think if you do enough to create the impression of the characters you are portraying then that should be enough.
I'm such a huge fan of the accomplishments made with Gollum that I really want to do the character as much justice as possible. Also to learn how to get as close as possible to being able to create that level of imagery in CG.
