In the 1970s, movies and television episodes started appearing warning us of dire consequences from our disregard for the environment and mother nature (remember Silent Running?). It's a shame we didn't listen then, and we're playing dumb now. Frogs has my vote for one of the best horror movie posters ever done. "Today the pond, tomorrow the world!"
How funny, Rob Kelly did a post on this film today, too!
