One of my favorite movies as a kid. I loved James Arness with his Thompson and the grizzled old scientist telling him where to hit the ten foot ant to kill it. We lived in SE PA. but used to drive out west to visit relatives near L.A. every year. I loved those dry concrete storm drains after seeing the movie for the first time. And I could make the keening ant cry too which creeped out my cousins.
It was a good monster movie, wasn’t it? I saw it when I was 9. A few months later, our family took a vacation to California. While we were staying at a trailer park in Los Angeles, I had to walk back to the trailer late at night, and a nearby car made the ant noise with a squeaking power-steering belt or some such. Well over 50 years, and I can still remember the feeling.
