(1952) Peggy Castle, Gerald Mohr, Can O'Herlihy, Noel Neill. The U.S. is being invaded! Unknown enemy troops pour over the borders. Bombs are dropping on major cities and installations, including an H-bomb on New York City at the film's riveting climax. Many of us saw this film on TV when we were kids, then, it just seemed to disappear. Very entertaining and must-see for all '50's sci-fi fans. 35mm.
