I was browsing through the Home Theater Forum website today, and I was looking at back posts for the Alien Quadrilogy topic. Of interest were four text articles/interview snippets that were posted by one of the members that cover aspects of Alien 3. Again, these may have been posted before, so forgive me if this is redundant.
The articles on there are:
"Mother From Another Planet" (from "The Insider's Guide To DVD")
This article was taken from the Insider's Guide To DVD book that was released in 2003. (Again, if someone is already posting this on one of the discs, and it's redundant, I'll remove this link), and examines the difficulty in shooting Alien 3. It was posted verbatim, save for one section regarding differences between all the script, but otherwise, the article's complete. It has interviews with David Fincher and Ezra Swerdlow.
Interviews with Richard Edlund (SFX Supervisor) on making of film, George Gibbs on the EEV Crash and Superfacehugger, Alec Gillis on the autopsy scene, and Fincher on what he wanted from the film
This piece is four different articles related to the production and editing of the film. I don't know if these are part of the Cinefex magazine articles, though.
Either way, you could always add them as text files for a nice little bonus to the third film. At least it's something.
