Star Wars:
Features - First part of interview with George Lucas (I think it's the original trilogy interview from the first THX set 1995) Very short.
3 original trailers - the first one with the logo coming toward the screen (no completed lightsabers), the second one (more action against the Star Wars logo) and Winner of 7 Academy Awards, Coming Back to Your Galaxy for Two Weeks Only
McQuarrie Production Gallery
The Movie starts out with a "THX Laser Disc" logo.
Empire:
Appears to be from the Definitive Collection (that's the logo on the title screen anyway). Audio is Dolby 2.0 Surround.
Commentary from Lucas, McQuarrie, Muren, Oz, and Ralston.
Has the THX Trench Run (opens up to a THX explosion ala the Special Edition and "The Audience Is Listening"
Other Extras: Chapter Selection, Audio Options (2 options), and Production Notes, and an "Easter Egg" Darth Vader that plays a tune called "Scoundrel" that is oh so not Star Wars.
The Cover shows it to be the WS letterbox 2:35:1 aspect ratio (so how can you tell if it's anamorphic or not??)
The front cover is the classic Empire "Gone With The Wind" and says "Digitally THX Mastered" at the bottom. The back has several montage shots on a black background.
There's also "supposed" to be another interview with Lucas, Original Teaser and Theatrical Trailers, Interview with Ben Burtt, walk through with Dennis Muren of the At-At Walker sequence (it's on the commentary, but not separate--is it supposed to be??) And finally no storyboard to film comparison of the asteroid chase sequence (unless it's hidden??!) Seriously, if I'm missing these, please point them out!
That's it for Empire (the most robust of this set I think)
Return of the Jedi -
Three Trailers - #1 - original Revenge of the Jedi, #2 - the changed "Return of the Jedi", and #3 final "Return of the Jedi" (which is rather stale sounding, but that's probably just the announcer who sounds like a theater manager or something...)
Also a rather lengthy interview with Dennis Muren broken into parts. Highlights include the Rancor, Speeder Bikes, a storyboard for the Endor space battle, the original slave girl video from Jabba's Palace, and a couple more.
Scene Index and main page with three faces - Darth Vader, Leia, and Luke, and something called the "DCS" which is just an advertisement.
The DVD Cover - the classic Return of the Jedi full cast poster
The DVD Back - "The Empire Falls..." Montage shots
The DVD - Starts with liquid rain Dolby Digital short. THX logo
And although not part of the set, I have a separate "making of Star Wars" told by R2-D2 and C-3PO that sure seems awfully familiar. Was this released as part of the "extras" DVD for the first SE DVD set?
