This week, the release of Revenge of the Sith completes a six-movie, 15 hour sequence in which the trilogy of films released in the last six years (The Phantom Menace, Attack of the Clones and now Revenge of the Sith) form a prequel to the original Star Wars films released between 1977 and 83, numbered parts IV-VI (A New Hope, The Empire Strikes Back and Return of the Jedi).
