Confronted by the terrors unleashed by Sauron, Frodo and his companions were aided by Aragorn, a Ranger and the last heir of Isildur, he who had taken the One Ring from Sauron in the first place. In time they came to Rivendell, and from there set out to destroy the One Ring. And Frodo struggled day by day with the burden of the Ring, for as he approached the boundaries of Mordor, the ancient land where Sauron had made the Ring, and where alone it might be unmade, the long dormant power of the Ring awoke and urged all evil things to help it return to its master. Though accompanied by trusted companions for much of their journey, Frodo and Sam eventually realized Frodo was a great peril to all who travelled with him, and they secretly slipped away from their company, unaware that Sauron's minions had found them and were attacking. In the final stages of the journey Frodo and Sam had to rely on each other, and they found deep within themselves a courage and friendship which sustained them as their steps drew them ever closer to the shadows of Mordor.
Film making is as much a science as an art.
To bring about the reality of J.R.R. Tolkien's Middle-earth, Peter Jackson has brought together artists and tecnicians from around the world. A special camera lens helps to focus on both actors so they seem to be closer together, and as long as their movements are properly coordinated, they appear to be a true man and hobbit on the screen. But sometimes it's necessary for a hobbit-sized actor to stand in for Frodo, and at such times Kirin Shah takes the role of the Shire's most renowned hobbit. Shah in fact portrays both Bilbo and Frodo in scenes where Gandalf must interact closely with the characters. Yet Kirin Shah's face will never be seen.
