Sean Astin is in final negotiations to play Sam Gamgee in New Line's live-action trilogy "The Lord of the Rings." Astin will play the servant and sidekick to Elijah Wood's Frodo Baggins in the adaptation of J.R.R. Tolkien's renowned fantasy trilogy, in which Frodo inherits a magical ring and embarks on a quest to save humanity from the sinister plans of Dark Lord Sauron. Director Peter Jackson is slated to begin shooting the first film, "The Fellowship of the Ring," this October in New Zealand. "The Two Towers" and "The Return of the King" will shoot immediately after, with principal photography on all three movies expected to last just over a year.
