Following the surprising success of his cheapjack Star Wars knockoff, Star Crash, Italian director Luigi Cozzi was given the helm of this cheapjack Alien knockoff. An alien cyclops causes a man to cover the Earth with nasty eggs (sometimes made of silicone, sometimes close-ups of common olives).
The eggs release gelatinous gunk which makes people explode, and it's all part of the alien's plan to take over the world. Cozzi, a less-talented protégé of Dario Argento, at least gets a good soundtrack by using his mentor's house band, Goblin, but delivers a bad film nonetheless.
The director admits that the ludicrous monster was made of badly painted papier-mache, requiring 96 separate cuts to look convincing in its big scene. It didn't work.
