In 2004, "The George Lucas Director's Cut" of the film was released. Under Lucas' supervision, the film underwent an extensive restoration and digital intermediate process by Lowry Digital and Industrial Light &amp; Magic (ILM), where the film's original negative was scanned, digital color correction was applied, and a brand new digital master was created. Computer-generated imagery and audio/video restoration techniques were also applied to the film.
