Them!

Them! (1954) is a landmark atomic-age sci-fi horror you can watch online on iFILM. Something is wrong in the New Mexico desert: shattered walls, untouched cash left by the bodies, victims killed in ways no one can explain. Police sergeant Ben Peterson and FBI agent Robert Graham start digging.

The clues don't add up to any human crime. Entomologist Doctor Medford and his daughter Pat arrive and piece together the horror: nuclear testing has bred ants the size of cars, and the colony is already on the move. Stop it in the desert or watch it spread past one small town to the whole country. The hunt ends in the storm drains beneath Los Angeles. James Whitmore, James Arness and Edmund Gwenn lead the cast, with a very young Leonard Nimoy turning up in a bit part.

This is the original giant-bug picture, the film that set the template for the 1950s wave of radioactive monsters that followed. It's a treat for fans of vintage science fiction and anyone curious where the whole subgenre began. Stream Them! (1954) online on iFILM.
