I first saw this film when I was only 7 and even then I knew there was something . . .well . . .different about it. For one thing those are the oldest looking teenagers I ever saw; then again all those JD movies offered actors who looked too old even for college in the roles of "kids" so we can't hold that fact against this film. The reason the aliens have come to our world is also atypical of 1950's films. They don't want to conquer the Earth, they don't want to re-populate a war devastated world. They are hungry and in need of a square meal and Earth is the perfect spot to breed the creatures they use as food! They call the creatures Gargans but they look a lot like lobsters. Of course since this is a science fiction picture, the atmosphere of Earth causes the Gargans to grow so large a single one could keep a Red Lobster in business for months! the effects budget was so low we never see the actual giant monster, just an empty travelling matte!
Most memorable are the ray guns used by the bad aliens . . .er . . .the intergalactic juvenile delinquents. As the original trailer said "They blast the flesh off humans!" and quite a few people get zapped into skeletons. There is one good alien, a sensitive fellow named Derek (David Love) who stands alone against his own people when he suggests they go raise their favourite meal on some other planet. Derek is unaware that he is the son of the leader of the planet, a fact which is not exploited nearly as much as it should be in this film.
The cast includes Harvey B. Dunn, best remembered as the police inspector in BRIDE OF THE MONSTER. Harvey was a professional clown and performed at parties with his trick bird (the bird appears in BRIDE also). Yes it's an offbeat film but worth a look. Get ready for a tearjerker ending that is telegraphed well in advance.
