After Blade Runner (1982) and Total Recall (1990) adaptations of the stories and novels of Philip K. Dick became much sought after. Screamers is based on a short story by Dick and scripted by Dan O'Bannon whose other science fiction work can be seen throughout this film (you'll spot the influence of Alien and Aliens). It's a science fiction story set on a remote planet where humans have discovered a rare mineral that can be used to supply unlimited energy for mankind. But mining it produces massive releases of radiation and a ten year war has been raging between the controlling mine company and the miners, the Alliance, due to bad safety practices and the deaths of miners. The Alliance have developed an automated biomechanics weapon known as 'screamers' that hunts humans . These are small machines that burrow under the surface of the ground and hone in on anyone not wearing an electronic tag. Henrickson (Peter Weller), an Alliance soldier, is ordered to travel to the enemy's command centre to discuss a possible ceasefire. He finds some survivors on the way including Jessica (Jennifer Rubin) and a young child but also discovers that the screamers seem to be self evolving and unresponsive to his tag. Made just before the advances in CGI this has some cool special effects and uses stop motion although the budget has restricted some of the film's potential. But the recreation of the desolate far away planet and the film's climax are impressive. The film has some quite shocking surprises too. There have been a few films where machines have become self aware and a threat, the Terminator series and The Matrix (199) for example, and films that look at the issue of what makes us human (Blade Runner being the classic example). Screamers delves into both these aspects and provides a good solid piece of scifi action adventure as a result. This has recently been re-released on DVD & BluRay and if you like a good, adult themed sci-fi then check this out, it's great fun.
