Day the World Ended (1955)

In a post-Apocalyptic world after an atomic war seven disparate people find themselves in a protected valley in the home of a survivalist and his beautiful daughter.

Invasion of the Saucer Men (1957)

A teenage couple accidentally awakens an alien after hitting it with their car.

Sci-fi comedy, clearly aimed at a teenage audience, isn't really that funny; the biggest joke are the freaky alien costumes.

Maltin (no star): "Science fiction with comic overtones, though done with so little finesse that it is difficult to know what is intentionally funny and what is accidentally so."

Maltin*1/2: "Slow-paced, minor sci-fi comedy...Cheap, but has some atmosphere and Paul Blaisdell's outlandish aliens."
