Alfonso Brescia, Italian director and movie maker, churned out 4 movies between 1977 and 1978. I have seen two of them and these films could easily be connected directly as sequels. Both have similar sets, costuming, and themes, and some actors are in both films. They are also equally as bad. So bad that I felt they disserved to be lumped together in one article.
All four films in the series are Italian low budget films that were put out to capitalize on the Star Wars craze. They have all the great elements of a sci-fi B movie Star Wars rip-off – space ships, rogue pilots, robots, aliens and disco music. These two films were shot basically back to back, obviously.
