In a space war, a tiny spaceship is hit by another one, falls on planet Earth into the hand of a little girl (Gracie) and penetrates her hand. Some time later, the private investigator Joe Keyes (Michael Biehn) is hired by a mother, who is under the protection of his former wife Monica (Joanna Pacula) together with her daughter Gracie (Lidsey Haun), to help her husband, the scientist Warren Rickman (Tobin Bell). Warren is being threatened by his colleague, Thomas Newmeyer (John de Lancie). Joe is divorced from Monica, and blames himself for the death of another mother and daughter who were under his protection. They were the wife and daughter of the detective Mack Waters (John Kapelos), and killed by a murderer Mack had put in jail. When Joe finds Warren, strange events happen and Joe decides to find Monica to realize what is happening and help her. A great mystery involving immortality and healing is disclosed along the story. This sci-fi movie is very intriguing, having a very different and unpredictable screenplay. It recalls a film noir, with narrative in off, dark and smoky places, with touches of `Blade Runner', and is a very good entertainment. With some improvement, it could have been an excellent movie. My vote is six.Title (Brazil): `Sangue Imortal' (‘Immortal Blood')

I've seen this movie many times and I think it's great. Sci-fi/film noir, how can you go wrong? Michael Biehn, John De Lancie, Steven Williams were all terrific. The effects were pretty good considering the budget (Less than $3M). Not enough humor maybe, but intriguing just the same. But then, I have a vested interest, don't I?

I watched this film expecting it to be a film full of villagers, but was pleasantly surprised to find that despite it's no doubt very low budget, some good special effects managed to be pulled off,(I especially enjoyed the alien being excremented through someone's hand-Nice), even though the film is a bit slow moving, it did keep you guessing (especially at the beginning), and had some good twists so I gave this film 7/10. There were above average performances from all cast members and some nice ladies, if you get the chance watch it, even for curiosity's sake.

Finally got around to watching my tape of the film being shown on BBC. At first I didn't recognise Michael Biehn and was about to trash it, but then I did and, on the basis of really enjoying him in Aliens, I watch Deep Red.Well at the end of ~90 minutes, I wouldn't say I was mentally challenged, but I'd still recommend it as a basic enjoyable movie -if you're into sci-fi, nanotechnology, and the good guy winning.
