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".

In Peter Jackson's "The Lord of the Rings" film trilogy, Gollum is a CGI character voiced and performed by actor Andy Serkis. He is smaller than both Frodo and Sam. Barely glimpsed in "" (2001), he becomes a central character in "" (2002) and "" (2003). The CGI character was built around Serkis' facial features, voice, and acting choices. Serkis based the iconic ""gollum"" throat noise on the sound of his cat coughing up hairballs. Using a digital puppet created by Jason Schleifer and Bay Raitt at Weta Digital, animators created Gollum's performance using a mixture of motion capture data recorded from Serkis and the traditional animation process of Key frame, along with the laborious process of digitally rotoscoping Serkis' image and replacing it with the digital Gollum's in a technique coined "rotoanimation". This work required a large number of digital artists. As in the animated depictions of the character, Gollum is shown as virtually naked save for a loincloth in the trilogy.
