I have 2 DVDs that are not the best quality but feature some of the items mentioned. Quality-wise this set is bad. The first disc features 2 things that would normally be presented fullscreen, however, they are centered in anamorphic widescreen - losing picture quality. Whereas, the 2nd disc is fine (all fullscreen), but the quality leaves a fair bit to be desired.

ALIEN ARCHIVES DISC #1:
Alien Director's Cut Documentary - Presented by Danny Boyle
Giger's Alien - Vintage footage of H.R. Giger at work on the designs for the film ALIEN

ALIEN ARCHIVES DISC #2:
Alien Evolution (Uncut) - Written and presented by Mark Kermode
Ridley Scott Interview - Don Shay of Cinefex magazine interviews Ridley Scott
Aliens: James Cameron: A Director and His Work - Exclusive visit to the set of ALIENS
The Making of Alien 3 - A rare look behind the scenes of the first three ALIEN movies
ALIEN 3 - trailer & international trailer
ALIENS - teaser trailer

Jonno:
I'd be interested in trading you the above 2 discs for your copies of the Evolution doco and Giger's Alien.
