Time for some of those "so bad they're good" movies...and these ones have semi-impressive casting!
The Devil's Rain, 1975, the year of my birth...mwah-ha-ha-ha...starring William Shatner, Tom Skerrit, Ernest Borgnine, Eddie Albert, Ida Lupino, Keenan Wynn and John Travolta in his extremely brief film debut! What an incredible cast for such a crappy-good film! Very much in line with the satanic-occult obsession of the 60s and 70s. Good fun, and lots of melty-faces.
Frogs, 1972...my favourite creatures! Eco-horror shlock at its finest. And another good cast: Sam Elliott, Joan Van Arl, Adam Roarke and the ever irascible Ray Milland--he is at his grouchiest here. If you love toads as much as I do (most of the amphibians "swamping" the people of this little island are actually toads--either Cane toads or Rococo and maybe some smaller species, too), you will love watching them cover the isle in a plague of themselves! Loads of other reptiles to ogle at, too.
