This fine drama is as much about unhappy newlyweds as it is about savage soldier ants that threaten a South American plantation. The killer ants cover a wide area, sweep everything before them and naturally are headed straight for Leiningen's cocoa plantation. The dislike between bride and groom nearly upstages the approaching army of ants. Eleanor Parker and Charlton Heston make a handsome couple but she seems to be everything he is not. Parker is confident, poised and self-assured while Heston is insecure, inadequate and out of his depth in her company. Perhaps this explains why he spends so much time trying to diminish her. The film leans heavily on the verbal sparring between Parker and Heston while building tension for the showdown with Marabunta. William Conrad is good in an early role as a jungle commissioner.
