This is the one in which the "villain" is a huge, carnivorous praying mantis. After the titular insect has attacked several people in a remote Arctic region, Col. Joe Parkham (Craig Stevens) swings into action. Parkham and his associates, Dr. Ned Jackson (William Hopper) and Ned's assistant Margie Blake (Alix Talton), track the predatory mantis as it heads southward to Washington DC (how did it get past customs?) The green monstrosity meets its Waterloo in "Manhattan Tunnel," where it is bombarded with poison gas (a little Raid or Black Flag might have come in handy). Some of the Arctic scenes in The Deadly Mantis were clumsily culled from the 1933 drama SOS Iceberg and a handful of Air Force training films.
