From Bleeding Cool:
The Alien Makers series of online documentaries by Dennis Lowe are must-watch videos for fans of the Alien series of movies, of which I’m addressing many, I’m sure.
Lowe worked on FX on the original film, as well as Legend, Labyrinth and The Empire Strikes Back, and interviewed many of his collaborators on Alien for his documentaries.
Most of the films can be streamed, or downloaded, from Lowe’s own website. Notably absent is Alien Makers 3, focusing on HR Giger and his incredible biomechanics designs.
Apparently, Giger was unhappy with the end result and requested Lowe remove it, which he did. I can’t really see what Giger would object to… but then I don’t see things quite the same way as Giger anyway. Less sticky goop and sexy pipes.
Today somebody has uploaded the 43-minute film to YouTube. I don’t know how long it will last, so you might want to get clicking now.
