As everyone and their brother knows, the original Star Wars trilogy will be released on September 21st. The discs look totally packed, and the fourth disc is of most interest to anyone I know.

Of course as with every time he releases these films, George Lucas had to change more stuff.

Episode IV: A New Hope. Only subtle changes here. The cantina shootout between Han Solo and the green-snouted bounty hunter Greedo is virtually identical, but now it seems their guns fire almost simultaneously. Lucas had changed the original for the 1997 rerelease because it seemed that Han had fired first. Also, Jabba the Hutt has gotten a makeover and looks more realistic in his scene with Han than when it was added in 1997.

Episode V: The Empire Strikes Back. The Emperor, whose face is seen in a hologram broadcast, goes uncredited, but he sounds and looks like Ian McDiarmid, who played the Emperor in Return of the Jedi and Senator Palpatine in Episodes I and II. (Clive Revill is listed as the Emperor in the Empire credits.)

Episode VI: Return of the Jedi. Christensen, who plays Anakin Skywalker in Episode II: Attack of the Clones and in the upcoming Episode III: Revenge of the Sith, now appears at the end of Jedi as Anakin’s spirit. He replaces Sebastian Shaw, whose face you still see when Luke Skywalker removes the iconic black Darth Vader mask. (In all three films, David Prowse wore the Vader suit, and James Earl Jones provided the voice.)

The thing I’m most looking forward to though is the bonus disc which will have a preview of the upcoming final chapter in the Star Wars Sextology; Revenge of the Sith. The disc will also include;

Episode III Behind the Scenes Preview: The Return of Darth Vader: Finally, Star Wars: Episode III will reveal just how Anakin Skywalker became Darth Vader, the most iconic villain in film history.

Also, experience how Hayden Christensen and Ewan McGregor have prepared for the epic lightsaber battle that has been anticipated for more than two decades: the climactic showdown between Anakin and Obi-Wan Kenobi.
