Them! (4K-UHD)

The first atomic test in New Mexico has produced a terrifying mutation: a colony of giant ants, grown to monstrous size by radiation, has been breeding in the desert and is now threatening to spread across the country. Gordon Douglas's Them! is the gold standard of 1950s creature features — a genuinely suspenseful, intelligently scripted science-fiction thriller that uses its monster-movie premise as a vehicle for real dread about nuclear anxiety, featuring outstanding work from Edmund Gwenn, James Whitmore, and James Arness.
