While J.R.R. Tolkien's Lord of the Rings trilogy has stood the test of time to become one of the best-loved works in the canon of fantasy literature, like much fantasy writing, its story also has a basis in fact. National Geographic: Beyond the Movie -- The Lord of the Rings: The Return of the King is a documentary which examines the production of Peter Jackson's epic film version of the final book in Tolkien's trilogy, but also explores the historical and geographical parallels between the fictional world of Middle Earth and real-world places and events. The documentary features interviews with Jackson and his crew as well as noted historians, and includes exciting clips from the picture.
