Frank Gorshen (TV's Riddler) and Lynn Oborne (from TV's Space Patrol) are the "adult" leads in the film. As traveling salesmen they find the saucermen and plan to make money by showing them around the country.
There is the "teenage" couple who also find the saucermen but are not believed by authorities. These are the two parallel story lines. This is one of the first movies to use the "teenagers save the world" theme that became popular during this period.
The saucermen makeup is well done by the makeup genius of that period, Paul Blaisdell. His balloon-headed, bug-eyed, mini-martians are still one of my favorites and their photos and other likeness still appear from time to time. Unfortunately, at the time of this review this movie is not available on Video or DVD. But we can hope!
