In a galaxy far, far away, long, long ago — say 1977 — the “Star Wars” sci-fi blockbuster and its sequels ruled the box office, raking in more than $4.3 billion worldwide from fans. Now all six films are available on Blu-Ray plus 40 hours of extras.

The set includes three additional discs of extras, with in-depth bonus supplements and extensive special features.

They include never-before-seen deleted and alternate scenes, and the 9-disc set also draws from an exploration of the exclusive Star Wars archives.

The first disc, with Star Wars Episode 1 The Phantom Menace, contains audio commentary from George Lucas, Rick McCallum, Ben Burtt, Rob Coleman, John Knoll, Dennis Muren and Scott Squires.

The first film, shot in 1977, actually became part “Star Wars Episode IV: A New Hope,” in the series.

The film became a worldwide pop culture phenomenon, and was followed by two sequels, released at three-year intervals.

Then, 16 years after the release of the trilogy’s final film, the first in a new prequel trilogy of films was released, again in three-year intervals. The final film was released on May 19, 2005.
