Who doesn’t love a giant ant movie? Who? Them! is at once high camp and a decent monster flick, thanks to a good-sized budget for sets and the dulcet voice of Edmund Gwenn, as a scientist who’s on hand to explain to the military — with educational films, even — why ants in the New Mexico desert have suddenly grown to a thousand times their normal size. (Hint: A-bombs!) Eventually we know they’ll have to go after the queen, just another big puppet that looks hysterically bad (and is really the only bad special effect in the film). But along the way we are treated to Gwenn, screaming at a cop with a machine gun to ‘Get the antennas! He’s helpless without them!’ Priceless.
