Frogs

Frogs (1972) is a low-budget eco-horror you can watch online on iFILM, directed by George McCowan. Wealthy tyrant Jason Crockett poisons every creature near his island estate. The swamp pays him back.

Freelance photographer Pickett Smith — an early role for Sam Elliott — arrives to shoot a pollution story and gets trapped at a family birthday party turned siege. Snakes, leeches, lizards and frogs close in from the water on every side. Ray Milland's cranky old patriarch refuses to believe it until it's far too late.

This one runs on pure drive-in charm: no effects, just real critters crawling across the frame and a nature-strikes-back premise played dead straight. Fans of vintage creature features will eat it up. Stream Frogs (1972) online on iFILM.
