Query: Good story. Cheap effects.

Although made with some truly cheap special effects, this is really one of the best films about alien invasion ever made. It could be said that this is the inspiration for The Arrival.Forrest Tucker stars in this film of alien invasion. Our characters wind up an small Alpine village where a mysterious cloud never moves from a nearby peak.We learn that there are horrible aliens in the cloud running experiments to transform the Earth's atmosphere into one more habitable for them.This is a seriously good plot and the first encounter with an alien is quite well done, but it is obvious at the end that there was not a whole lot of budget for special effects.This one is fun and well done. A must-see for fans of suspenseful alien movies.
