The best Roberto Dell'Acqua’s science fiction movies

When a terrorist's body, infected with a stolen chemical, is recovered by the US military, the corpse is cremated, unintentionally releasing the virus/bacteria into the atmosphere over a small island. Soon the infected populace mutate into flesh-hungry zombies, and a trio of soldiers on leave must team up with a group of tourists and board themselves up in an abandoned hotel as they try to fend off the agile and aggressive living dead.

A young humanoid alien who gets stranded on earth hooks up with a grizzled old sheriff in a western town and tries to help him solve a tough case, but the sheriff doesn't want any help from a "kid."

Earth is attacked by an intergalactic villain and his army of robotic androids.

Somewhere deep in the jungle a chemical corporation dumps tons of toxic waste in a still active volcano. Two environmentalists try to expose these illegal ways of getting rid of hugely dangerous waste, but they get caught by the vigilantes working for the company. One of them, the super-hot Maria Giulia Cavalli, manages to escape and she is saved by a snake farmer who lives alone in the jungle. Together they try to bring down the company, but it’s too late. Years of chemical poisoning have spawned a deadly monster that is set out to exact revenge on humans that have unknowingly brought him to life. Directed by legendary Antonio Margheriti, the unholy master of Italian B movies, Alien from the Deep is one of the most beloved Italian rip-offs. A wildly entertaining ride, the movie is an inventive crossover where lots of different genres and styles are mixed.
