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".
The Hunt for Gollum
The film is set during the timespan of "The Fellowship of the Ring". It takes place 17 years after Bilbo Baggins's 111th birthday party and just before Frodo Baggins leaves the Shire for Rivendell (an interval which was not outlined in the ). The wizard Gandalf fears that Gollum may reveal information about the One Ring to the Dark Lord Sauron, and sends the Ranger Aragorn, heir of Isildur, on a quest to find him.
