Love that movie. But, I like Chuck Norris in general
My turn.
A movie in which a satelite crashes back to earth. Upon being sent to retrieve it, the recovery team discovers that everyone in the small town is dead, except for a wino, and a baby.
The recovery team takes this satelite, and the biological organism it carries ,to a secret lab in the desert for study.Just when this team has figured out how this organism works, and how it can be stopped, an accidental release of this bug, near the end of the movie, causes the computer controlling the complex to activate a countdown for a small nuclear warhead, for self-destruction. It is then a race against time, lasers and poison gas, to stop this countdown.
