A Viking probe from Mars comes back to earth and is being studied in a science facility until the military come along to acquire it for themselves. But the probe has brought something back from Mars and it escapes into the facility. Cue lots of chasing around badly lit corridors as two scientists and a few soldiers try to find it. An unoriginal plot is acted out by a cast light on charisma so it becomes a rather tedious film. The soldiers act stupidly and the scientists make amazing assumptions based on no evidence. The best thing is the alien itself, simian and insectoid at the same time and the other gooey alien bits are good too. Unfortunately a good alien can't redeem an otherwise unexciting movie

If you like smart Sci-Fi you will like INVADER aka LIFEFORM. A Viking probe satellite mysteriously returns from Mars and like a Trojan Horse has a surprise in tow. A strange pod resembling an armadillo spawns a creature with a taste for blood and the curiosity to gather intelligence of Earth's inhabitants. The curious visitor takes on the form of an armored ape... albeit angry and clever with the ability to transform its shape. The story line is well thought out, but too similar to most "alien" movies. Is the Martian hitchhicker trying to prevent an invasion of the red planet? An abrupt twist at the finale leaves a few questions unanswered. The cast includes: Deirdre O'Connell, Cotter Smith, Leland Orser and Ryan Phillippe.

I caught this film on the Sci-Fi Channel. They were hyping it as a Ryan Philippe movie, though this is clearly not so. He plays a very minor part in the story. That's the Sci-Fi Channel for you.The important thing is that this movie is not that bad. It suffers from lack of style, lack of cinematography, poor pacing and some annoying "rigidly following the groove of the genre" plot paths.However, there are some good things.The actors are high quality and deserve a shot at better films. Their characters suggest depth and background, making them almost well rounded, though such depth and background is only suggested (not demonstrated) in the film. The portrayal of the scientists and military types is non-cliched. They are intelligent and have intelligent dialog. They behave as real people would.The science details are actually based on science and smarts, instead of gadgetry and nonsense. It is clear, as mentioned in another good review, that the scriptwriter researched the material, as there are correct descriptions of the Mars lander's capabilities and design and interesting concepts about the alien lifeform are explored.The alien lifeform is extremely well thought out and designed. It looks great on screen, too. It is possibly the most interesting thing about this film, though treated a little more like the "creature we must hunt down and kill" than I'd like. It does demonstrate interesting behaviors and qualities not seen often before, as well as something most alien creature movies never consider: intelligent motivation.The film does not end predictably and the process the film takes to get to that end is not that bad, either. It's just a bit anticlimactic and a little flat.This review may sound unkind. I am simply being realistic and honest. The flaws are there and they keep this film from being high quality. Yet, there is much to like. The good aspects are plenty and are of higher caliber than you would expect to find in direct to video alien-invader flics. Normally these kinds of films rely of cliche, unintelligent characters, unrealistic scenarios, sex, gunplay and gore. This film uses mostly none of those items to make its attempt at entertaining you (some violence and gunplay, but not to rediculous extremes).I found much to enjoy about the film, from a deconstruction point of view - the technical details, the story concept, the unique uses of the genre, the excellent alien design and portrayal, and as a general "learning tool" for film study.As a feature film, it falls flat. As an extended length episode of The Outer Limits, it would have been a "top-ten" episode.I think that anyone who can enjoy "flawed films with good intent" should give this film a shot; it isn't grade-A material, but it's worth a viewing or two and may inspire film makers to do better in different ways.

Although it was a 'direct-to-video movie', it was nice. Convincing characters and a well thought out plot, for a B-movie. Pretty good special effects and a very nice (and unexpected) climax. If you like s-f movies you should see this movie. 7/10
