Watch Lifeforce Online – Free Streaming Lifeforce 1985 Full Movie HD on Putlocker and 123movies. “Lifeforce” is a great sci-fi movie, with a story that uses the storyline of Alien entwined with zombie apocalypse movies. The most curious is that the gorgeous and sexy actress Mathilda May works naked all the times. I had seen this movie on 23 January 2001 and 21 Dec 2001 and I liked most than today. The plot has flaws but it worth to see this movie, not only because of Mathilda May, but because it is a good story.
