Statistically, this movie was a hit. Made for $200k, it grossed over $2 mill in the US alone. This was the secret of success for American International Pictures. Keep the budgets low, and the base of horror fans will show up and you'll make a profit. 1972 was the year for horror. A large number of films catered to the horror fan, many were cheaply made. But they all made a profit. Frogs is an example of a movie poster created before the movie was filmed. Frogs don't kill anyone in the film, but they made a cool poster. So they were thrown into the mix of alligators, lizards, snapping turtles, snakes, spiders, etc. Since many of these creatures make people queazy, it must have seemed like a slam dunk to film- fearmakers. However, the animal performers are less than convincing. Especially the alligator, where producers sped up the film to make him look like he's moving quickly. The acting is as good as can be expected for this type of film. Joan Van Ark and Sam Elliot debut here (Van Ark had done a soap). Milland is good as the cranky old rich stereotype. If you're looking for a "tame" horror picture to keep the kids interested, this might be it. For adults, it's value is mainly nostalgic.
