Years later, the BBFC classified the uncut version with a 15 certificate. It was released on home video in the United States under the titles "Alien Contamination" and "Toxic Spawn", which are both heavily edited. Cozzi later revealed that Cannon Films, the film's North American distributor, had changed the name to "Alien Contamination" in order to capitalize on the popularity of Ridley Scott's "Alien" (1979). It is now available in the US in an unedited version which has been released on DVD.
