The blurb:
“While working on the designs, sets and costumes for Alien, H.R. Giger maintained detailed diaries of the process; later these would be published in the form of ‘Giger’s Alien’ (1979) and the comprehensive ‘Alien’ (2013).
At the same time, his girlfriend and assistant Mia Bonzanigo was a frequent visitor on set to photograph and document proceedings. She filmed the planning and making of Giger’s creations on 16mm, and after the main production was complete, Bonzanigo and Giger edited their footage into a personal behind-the-scenes documentary. Though it provides an outstanding insight into Giger’s contribution to the film, the documentary has remained surprisingly obscure. Clips can be seen in the various official making-ofs on Fox’s laserdiscs, DVDs and Blu-rays, but the full documentary has only been properly released on a very limited VHS from Giger’s museum, and a 1987 Japanese laserdisc, which is presented here.”
