Forbidden World, originally titled Mutant, is a 1982 American science fiction-horror film. The screenplay was written by Tim Curnen, from a screenstory by R.J. Robertson and Jim Wynorski. It was co-edited and directed by Allan Holzman, who had edited Battle Beyond the Stars two years earlier. The cast includes Jesse Vint, Dawn Dunlap, June Chadwick, Linden Chiles, Fox Harris and Michael Bowen. Forbidden World has also been released under the titles Mutant and Subject 20. The film received three nominations for the 1983 Saturn Awards: Best Low Budget Film, Best Make-up and Best Special Effects. It was generally panned by critics as a cheap, exploitative imitation of the movie Alien, with sex, nudity, uneven editing, cheap special effects, and a sound design which some moviegoers found unpleasant, although the electronic music score produced by Susan Justin received mostly positive attention. It is frequently paired with and compared to the previous year's Corman-produced Alien rip-off Galaxy of Terror, with which Forbidden World shares some of the same sets (designed by James Cameron). The movie also makes use of footage recycled from the 1980 movie Battle Beyond the Stars, which was also produced by Corman. The film was remade in 1991 under the title Dead Space, on which Corman served as executive producer. The remake has minor variations but still retains the plot and character stylings of the original, also referring to the mutated virus as a "metamorph" as the original did. Plot In the distant future, at a genetic research station located on the remote desert planet of Xarbia, a research team has created an experimental lifeform they have designated "Subject 20". This lifeform was built out of the synthetic DNA strain, "Proto B", and was intended to stave off a galaxy-wide food crisis. However, Subject 20 mutates rapidly and uncontrollably and kills all of the laboratory subject animals before cocooning itself within an examination booth. Military officer Mike Colby, accompanied by his robot assistant SAM-104, is called in to investigate the problem. After Colby settles in, his decision to terminate Subject 20 to prevent further deaths is met with research-minded secrecy and resistance. The staff of the station includes the head of research, Gordon Hauser, his assistant Barbara Glaser, lab assistant Tracy Baxter, lab technician Jimmy Swift, electrician Brian Beale, the station's head of security, Earl Richards and Cal Timbergen, the medical doctor. When Subject 20 hatches from its cocoon,
