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".

Jackson expanded on the difference, saying that "Sméagol is a joyful, sweet, character. Sméagol does not lie, deceive, or attempt to manipulate others. He is not evil, conniving, or malicious – these personality traits belong to Gollum, who should never be confused with Sméagol. Sméagol would never dream of wielding power over those weaker than himself. He is not a bully. In fact, he is very loveable." Elijah Wood, who portrayed Frodo in Jackson's films, called the incident "horrifying".
