This third and final installment of Peter Jackson's adaptation of J.R.R. Tolkien's "Lord of the Rings" novels begins with Gollum (Smeagol) remembering his first encounter with the powerful ring, and how he strangled a friend to gain possession of it. Gollum is central in the film, and he although he continues to waver between his two conflicting personas, the one that will do anything to regain possession of the Ring begins to take over.
The movie shifts between Sam and Frodo's journey to Mount Doom to destroy the ring and the remaining members of the Fellowship's quest to fight the impending forces that threaten to end the time of man. Sam and Frodo are being lead by Gollum towards Mount Doom, but Sam soon begins to doubt Gollum's intentions and fears for Frodo's life. Frodo, meanwhile, remains determined to see the best in Gollum and believes that they need him for their journey.
Gandalf, Aragorn and the rest of the remaining members of the Fellowship join with Theoden and the legions of men to fight the evil Orc forces in the Siege of Minas Tirith and the Battle of the Pelennor Fields. The two parallel story lines finally come together in the end as Aragorn leads an army of men in diverting the Eye of the Enemy away from Frodo and his mission of destroying the Ring in the fires of Mount Doom.
This film is rated PG-13 for epic battle sequences and some scary images.
