It isn't so much about the making of the movie itself, but rather about the many inspirations for the movie, as well as taking a closer look at the filmmaking and what makes it so great and unique. This documentary is short, it's only 90 minutes, and it doesn't really go too deep into anything, but it's an enjoyable watch if you're a fan of the movie. What this documentary definitely has over most other making-of documentaries is style. This is a very stylish and good-looking documentary! The interviews are framed and lit in such a cool and interesting way that you just don't see very often and the old footage they show is all very interesting to watch. Overall, this is worth a watch for any fan of Alien. It doesn't really say or show anything new, but sometimes you just want to revisit an old favourite from another point of view. This movie does that very well.
