The Crockett family, led by Jason (Ray Milland), may have great power and influence, but nature in no way cares about those things. Snakes, birds, geckos, alligators, turtles, butterflies and, yes, frogs, are prepared to end their lives for daring to abuse the ecosystem with pesticides.

Wildlife shutterbug Pickett Smith (Sam Elliot) picked the wrong holiday weekend to be in their Florida mansion.

Directed by George McCowan, whose career often found himself working in episodic television, and written by Robert Hutchison and Robert Blees (Whoever Slew Auntie Roo?, Dr. Phibes Rises Again), I am sad that I will never live the life of drive-in aficionados of 1972 who got to see this with Godzilla vs. the Smog Monster.

I have no idea if the animals are turning on all of humanity — I mean, Jason’s dog remains loyal — or if it’s just this family, but I love the swampy world that this movie makes, one that makes nearly every creature in the world outside the Crockett home into a killer ready to work together and wipe out rich folks.

This also has tons of stock footage of animals which is how you make a low budget movie about a whole bunch of animals. As it was, the hotel everyone was staying in was adamant that no animals were allowed to stay in the actor’s rooms, as if that would be a thing.
