Classic 1950s science fiction movie, released in 1954. Directed by Gordon Douglas and written by Russell S. Hughes and Ted Sherdeman, the film starred James Arness, James Whitmore, Edmund Gwenn, and Joan Weldon (with a cameo appearance by Fess Parker!).

The plot revolves around the discovery that nuclear tests in the New Mexico desert have caused ants to mutate into giant monsters. Killing one nest of giant ants is hard enough, but when two queens escape the nest, the hunt for the killer insects intensifies.

The film's special effects are a bit primitive (hey, it was a low-budget flick--they did the best they could), but the acting is first-rate, the dialogue is outstanding, and the story is intelligent and genuinely suspenseful.
