One of the first of the atomic backlash films (1954), with a herd of giant ants overrunning a nuclear testing ground in the southwestern desert. Decently budgeted and atmospheric, it’s a sober accomplishment in a cycle that would quickly turn to self-parody. Directed by Gordon Douglas, a steady hand; with James Whitmore, Edmund Gwenn, Joan Weldon, and James Arness. 94 min.
