When the Viking space capsule suddenly returns to Earth from its long ago trip to Mars, it brings with it an intelligent visitor that is part "Alien" and part "ET". Encased in armor, it extends a humanlike form from its shell to examine its surroundings and shows an interest in humans including a soft caress of a female scientist prior to the Army killing it. This only enrages its sibling. Written by John Sacksteder <jsackste@bellsouth.net>

Alien rip-off #407573-B
12 July 2007 | by unakaczynskiSee all my reviews

Lifeform (AKA Invader) 1996 R

This film is about a team of scientists and military yahoos that end up fighting an alien creature. It's that simple. It's yet another film like Alien or Leviathan (which itself was a direct rip-off of Alien) or Species. In this one, intelligent life that reproduces asexually sends a Viking probe back from Mars (because Mars is new territory in the world of alien encounters you know), and that probe has been modified to carry this creature along with it. Of course, the alien gets out and gets hunted and gets killed.

Overall, the acting isn't too bad, and the special effects are competent. The alien is intelligent, so of course, the one woman in the film feels sorry for it. The design of the alien itself is kind of like those half-human, half-horse creatures. You know, a centaur. It looks all terrifying on the outside, but then it extends it's little alien body up (the part where the human part of the centaur goes) out of the normal trunk (the part that is the horse), and it looks all benevolent. The military base they're on is rather bland, and of course, Big Brother shows up and spoils the show. The Army folks saunter about trying to kill the alien and they're all afraid it may have some contagion that it's spreading around.

The atmosphere isn't bad, but the film is somewhat shallow—it's just a straight-forward science fiction/horror flick with some decent gore and a humorous kill (guy is stabbed with the blunt end of an M-16). Nothing really special, but nothing really horrible. Recommended to hardcore SF/horror buffs. And that's about it.
