This movie is a HOOT! Unintentionally, of course--which makes it all the better. Dean Stockwell moves through most of the movie like he's heavily sedated (or maybe in shock at finding himself in such a bad movie), only coming to life in the film's climax.

Poor Sandra Dee--the eternal virgin--has to learn the hard way never to give strange young men a ride home from the library.

Psychedelic "special effects" complete the experience...all of it taking place in the accursed hamlet of Dunwich...but I won't spoil the fun by saying any more. Let me just add that I am a fan of Lovecraft's & should have been miffed at this botched attempt...but I was too busy laughing.
