DIE MONSTER DIE (1965) Stars Boris Karloff and Nick Adams. Based on H.P. Lovecraft's story "The Colour of Space." A cosmic meteor crashes to earth, bringing with it powers that can't be controlled. Karloff is trying to harness the power, but all around him vegetation...and people are rotting away...turning into monsters. There's a green house full of creatures that look like the ugly robber monsters you used to stick on the top of your pencils in elementary school. Pretty cool.
THE DUNWICH HORROR (1970) Stars Sandra Dee, Dean Stockwell, Ed Begley and Lloyd Bochner. A creepy young man shows up in a local library and steals the Necronomican, a book on the mystic evils of a long-forgotten race of supernatural beings. Then things start getting tense as weird forces are released and the young warlock has eyes for taking Sandra Dee into a different dimension with him. Based on H.P. Lovecraft's classic story and full of drive-in horror weirdness!
