13. Today The Pond! Tomorrow The World! - Frogs
The original poster for 1972s Frogs shows a human hand hanging out of a giant frogs mouth, which in true exploitation fashion turns out to promise more fun than the picture delivers. A dreary nature-strikes-back film sadly devoid of giant man-eating frogs, it depicts swamp wildlife turning against an avaricious family headed by Ray Milland. Ho hum.
