Composer John Williams completes the Star Wars saga with his stirring score for Revenge of the Sith. The signature theme that encompasses the drama, betrayal, and excitement of the film’s climactic acts has been developed as a music video, entitled A Hero Falls. Featuring footage from Episode III, the music chronicles Anakin's descent to the dark side and the final confrontation with his former mentor and friend, Obi-Wan Kenobi.
