"ST:Nemesis" came out in December 2002 and since then feature-length documentaries of making-of the films have become pretty regular on DVD 2-disc editions.
To be fair when I wrote that I hadn't see some of the special features from DS9
, and Enterprise
It was nice that Paramount mined vaults for the 1987, 1988, 1992 era interviews for them. Surprised that the Star Trek: TNG: Season 2: Disc 6
had 2 interviews that were shot on 16mm color negative film (you could see the white dust specs and occasional hairs). It gets my hopes up for the announced 'Gene Roddenberry's vision'
that will be on the STXI Blu-ray. Hopefully they will use old 16mm film footage of him from the 1960s.
behind-the-scenes footage were all shot in 16:9 widescreen and it's a nice touch.
