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: How We Made Movie Magic
"Gollum" details how a three-week commission for Andy Serkis to provide a voice-over for Gollum grew into a five-year commitment to breathe life and soul into "The Lord of the Rings"' most challenging creation. Andy Serkis tackles various subjects throughout the book, including character conception (Gollum's "cough" is derived from his cat coughing up a hairball) as well as the hard work it took to act out Gollum and replace it with CGI. He also discusses the controversy of whether he should have been eligible for an Academy Award for his work as Gollum.
