The three stars out of ten is because of the fun I had laughing at this god-awful movie. Absolutely hysterical. Ridiculous monster, a totally unbelievable Kerwin Matthews, and Pier Angeli, who died shortly after this film was completed. I watched the entire movie fascinated by two things, the horrible monster costume, and Pier Angeli, who was once a very promising young actress back in the 1950's. She still looked good, but what a waste for her to act in something like this. Even more sad is that this apparently was her final acting job. Very sad. It is hard to believe that this was the only role that she would be hired for. I had read that she had hoped to act in The Godfather, and also that she had overdosed before finding out that she had been hired for a role on Bonanza. Does anyone know if she accidentally overdosed, or did she commit suicide?
