John Frankenheimer directed this wonderful little film about a lumber company whose mercury gets into a local water system and starts to mutate the wildlife in the forest. The result is huge fish and tadpoles, wildlife going crazy and a huge mutant bear-like monster that is still damn scary to this day.Robert Foxworth and Talia Shire are a couple from new York who travel to Maine to fin out what the trouble is, and they find out in a big way. The Indians and the lumber company are at odds and people are being killed by the mutant bear in growing numbers.
The tension builds slowly and soon everything comes down to a battle of survival between the mutant and a few survivors. The rest of the cast is excellent including Armand Assante, Richard Dysart and Victoria Racimo. Critics tore this film apart and there was no reason to. It is exactly what is it supposed to be...an entertaining monster movie. When I first saw it, it blew me away and it still does.
