Not sci-fi, but Richard
Not sci-fi, but Richard Stanley related (the director of Hardware), as back in 1990 he made a documentary that’s pretty interesting in the post-9/11 world – he went to Afghanistan during the Soviet invasion, and his film crew followed a group of Taliban (possibly actually Al-Qaida, can’t remember exactly) rebels and civilians during and after the conflict. It’s not narrated, just the Afghanistan landscapes and people backed by Simon Boswell’s soundtrack.
I’ve heard one of the camera men was killed in combat during the shooting of the film, though by the looks of it that isn’t true, might be possible someone confused that with a later event, as camera man Carlos Mavroleon is the only credited camera operator that is listed as dead on imdb, and he was killed under similar circumstances when shooting a documentary in Pakistan for Frontline in 1998 (about 10 years after they shot this).
It’s worth checking out imho, the entire documentary is included as an extra feature on the Dust Devil DVD, which is also an excellent film by Richard Stanley. Imdb page: http://www.imdb.com/title/tt0275056/
