Alien 2: On Earth was released in 1980 and directed by Ciro Ippolito and produced by Luigi Cozzi. The movie follows a group of cave explorers who discover a mysterious living rock in an underground cavern. They soon realize that the rock is home to deadly creatures that are hell-bent on destroying the entire human population.
The film is an unofficial and unauthorized sequel to Ridley Scott's 1979 classic, Alien. However, other than the basic premise of humans being hunted down by extraterrestrial creatures, the plot has little connection to the original film. In fact, the film was originally titled Alien 2, but the title had to be changed due to copyright issues.
The film is widely regarded as a low-budget B-movie and received mixed reviews upon its release. The effects are notably cheap, and the acting is often criticized as wooden and uninspired. However, the film has gained something of a cult following over the years due to its cheesy dialogue, bizarre soundtrack, and over-the-top gore.
Despite its flaws, Alien 2: On Earth is an entertaining horror film that is worth a watch for fans of low-budget sci-fi and horror movies. Just don't expect anything resembling the quality of Ridley Scott's Alien.
