(1954)
This year's Halloween Movie Madness is full of a bunch of movies I have never seen before, and three of those movies are about ants. The first of the three, THEM, came out just over 20 years before I was born..
THEM is a movie that stars Marshall Matt Dillon (James Arness), Mark Twain (James Whitmore), and Santa Claus (Edmund Gwenn) facing off against giant, mutated, radioactive ants in New Mexico and Los Angeles.
