I just checked the TV guide and am devastated to discover I missed this fine Hollywood production:
The Hive (2007)
A horde of flesh eating ants go on the rampage, slaughtering a group of mine workers in Thailand. A scientist is sent to wipe them out, only to clash with a conservationist old flame who hopes to find a way of containing the threat without destroying them. They soon find themselves forced to join forces to survive, however, when it emerges that the carnivorous insects have evolved a sinister intelligence and have deadly plans for the human race. Thriller, starring Kal Weber and Elizabeth Healey
It would appear to have enough plot lines to keep four or five movies going! And it all sounded so plausible too, until they just had to add the sinister intelligence bit….
Damn those conservationist old flames, always popping up at the most inconvenient moments.
