Did You Know?


In the laboratory, above the filing cabinets on the right was a aerial picture of the K-25 Plant, it was the largest building in the Manhattan Project and was authorized in late 1942, it was 11 miles from the WWII Secret City of Oak Ridge, Tenn. The plant was intended to produce enriched uranium. The photo on the left looks like it is a close up of K-25 but that has not been proven at this time. See more »


The shoreline scenes show breaking surf. The Salton Sea is a lake where the waves never get more than a few inches high, even in a high wind. See more »

Enjoyable old sci-fi film

First of all, the title suggest one single monster, but there's several of them in the film, pretty good looking monsters for a low budget indeed, and they did not challenge the world, just a few people in the Salton Sea area actually, but that's OK, it's part of the 50's charm. In fact, "The Monster..." is far better than others "big bugs" films of the era, maybe slow paced, but with a clear plot, tension and good performances by the cast. Believe me when I tell you: this movie deserves a remake! Is not difficult to imagine a version today, with best production and far advanced special effects... even more if you consider that the other feature in this "Midnite Movies" DVD is "It!", a direct source of inspiration for "Alien". Good old sci-fi stuff!
