Frogs (1972)

Ray Milland plays an aging, grumpy, physically disabled millionaire who invites his family to his island estate for his birthday celebration. Sam Elliot plays a free-lance photographer who is doing a pollution layout for an ecology magazine. Jason Crokett (Milland) hates nature, poisoning anything that crawls on his property. On the night of his birthday the frogs and other members of nature begin to pay Milland back.
