Gollum
Gollum is a fictional character from J. R. R. Tolkien's legendarium. He was introduced in the 1937 fantasy novel "The Hobbit", and became an important character in its sequel, "The Lord of the Rings". Gollum was a Stoor Hobbit of the River-folk, who lived near the Gladden Fields. Originally known as Sméagol, he was corrupted by the One Ring and later named Gollum after his habit of making "a horrible swallowing noise in his throat".
Gollum
Serkis once again played Gollum in the prequel film "The Hobbit: An Unexpected Journey", released in 2012. In the film, Gollum drops the Ring while killing a goblin, rather than having lost the Ring by the time Bilbo finds it. Gollum also appears in "The Hunt for Gollum", the independently-produced 2009 prequel to the Jackson films directed by Chris Bouchard. Bouchard's CGI Gollum is directly inspired by Gollum in the Jackson films.
