Who played Gollum in The Lord of the Rings?

Answer 1

Andy Serkis was the voice of Gollum. They used many of his facial features and expressions and movements for the animated Gollum.
Andy Serkis voiced Gollum and acted the part of Smeagol when he kills his friend Deagol. The facial features of Gollum are loosely based on those of Serkis, and the body movements of Gollum were created in such a way that they would match the voice and sounds that Serkis had him make. (Something that I found interesting is that Serkis based many of Gollum's sounds on those made by his pet cat.)
Gollum (Smeagol) was played by Andy Serkis in the films and will also be played by him in the up and coming 'Hobbit' films
