Raunchy 80s Space Movie Is An R-Rated, Sci-Fi Exploitation Worth Streaming

The impact that 1979’s Alien had on cinema and pop culture at large is undeniable. There have been countless imitations since its release, with 1982’s Forbidden World being one of the earliest examples. Using the same Alien blueprint that films like The Last Days on Mars (2013), Ash (2025), and Underwater (2020) shamelessly cling to, Forbidden World is more true to form in its depiction of a hostile alien takeover, but it leans harder into gore, sex, and low-fi B-movie spectacle than most films that share its DNA.

Speaking of DNA, what sets Forbidden World apart from Alien is its characters’ willingness to poke and prod at the very alien lifeform threatening their survival, fully aware of how much trouble it could cause. Alien centers on a hostile organism that nobody aboard the USCSS Nostromo intended to encounter, while the crew in Forbidden World could have avoided catastrophe entirely if they had simply aborted their mission and terminated their test subjects in a controlled environment.

Like Alien, But More Violent And Sexy

Forbidden World opens with a familiar setup, taking place at a research station on the distant desert planet Xarbia. The film wastes no time establishing its gooey, bloody, gestating antagonist, Subject 20. We’re introduced to visiting military officer Mike Colby (Jesse Vint), who, alongside his trusty robot SAM-104 (Don Olivera), urges head researcher Gordon Hauser (Linden Chiles) to terminate the experiment after witnessing the dozens of slaughtered animal carcasses littering the “creature room,” clearly victims of Subject 20’s violent metamorphosis.

Accompanying Gordon in his study of Subject 20 are assistants Barbara Glaser and Tracy Baxter, who, for reasons the movie never bothers to justify, are almost always scantily clad in space uniforms that may as well be short sun dresses or bath robes. Rounding out the crew are lab technician Jimmy Swift (Michael Bowen), electrician Brian Beale (Raymond Oliver), security officer Earl Richards (Scott Paulin), and Doctor Cal Timbergen (Fox Harris).

When Jimmy carelessly opens Subject 20’s enclosure after being ordered to clean up the piles of animal bodies in its wake, he becomes the first victim of the creature’s violence, though he isn’t killed outright. Dr. Cal examines Jimmy’s barely alive body and discovers that Subject 20 has infected him with a mutated strain known as Proto B. The infection reduces human DNA to a uniform protein mass, effectively turning the body into a blank slate that Subject 20 can consume, only making it stronger.

As Forbidden World moves into its second and third acts, Subject 20 goes into full rampage mode, hunting down the rest of the crew and annihilating everything in its path as it grows exponentially stronger and inches closer to its final form.

Let’s Just Call It What It Is

For a movie that would not exist without Alien, Forbidden World still has a lot going for it, along with enough B-movie charm to stand on its own. The key distinction is that Alien follows a crew that unknowingly brings a hostile lifeform aboard their ship and pays the price. Every crew member in Forbidden World, on the other hand, understands the dangers they are facing and even receives orders from the military to terminate the research once Subject 20 proves dangerous.

This willful ignorance separates Forbidden World from the film that inspired it because the characters more or less know what they are getting into and choose not to exercise caution. When Subject 20 finally launches its slasher-style rampage, the violence is easier to stomach because everyone here had ample warning. Alien’s characters are sympathetic because they were deceived into transporting a Xenomorph. The crew in Forbidden World is essentially asking to be slaughtered inside their own research station because they know better and press on anyway.

Thanks to these tonal differences, Forbidden World works as a shameless copycat that still manages to carve out its own identity. Exploitative, sexually charged subplots notwithstanding, there are still some great creature shots, and the gore is surprisingly solid for an early 80s, low-budget riff on a much more successful intellectual property.

A slasher-style Alien copycat that commits fully to its sleaze and splatter, Forbidden World is a solid watch for these reasons and can be streamed for free on Tubi as of this writing.
