There is really only one good reason to watch Daniel Haller's The Dunwich Horror, and that's for the trippy animated credit sequence (complete with a jazzy / psychedelic Les Baxter score) that seems to feature a man and a pregnant woman searching for a place to give birth. One can not help but see allusions to Mary and Joseph seeking out a barn ... of course when the hapless animated couple are devoured by a daemon, it's easy to understand that this is not the greatest story ever told - in fact, as the movie progresses, it's more, the dullest story ever told.
Once the credits are over, the plodding story of Wilbur Whateley (Dean Stockwell), and his search for a virgin (to be used for nefarious doings) is told - and what a confusing, convoluted tale it is. Wilbur's family has a deep dark secret, his mother is locked away in an asylum, his brother is an inter-dimensional monster who causes LSD-trip-like lights to flash whenever he's around, his grand father walks around all day carrying a staff, and none of the people in the charming town of Dunwich seem very fond of poor Wilbur. Oh, and he's also prone to stare at you with his mesmerizing eyes.
One day, Wilbur set's his gaze on the virginal Nancy (Sandra Dee), and before you can say, "Cthulhu", she is under his spell, moving into his creepy Victorian mansion, drinking spiked tea, dreaming of being ravaged by colorfully painted cultists and just staring off into space - This is certainly Sandra Dee's finest performance.
look at me, I'm Sandra Dee, lousy with virginity...
For some reason, a few folks notice that Nancy is missing and they go searching for her, and show up at Wilbur's mansion (which from the exterior, looks like a farm house decorated for a Rob Zombie film).
OK, so a lot of other stupid stuff happens, and eventually Talia Shire (billed as Talia Coppola) even shows up as a gossipy nurse...
Rocky, you can't win!!!! - oh wait, wrong movie.
Finally, the monster brother escapes his room, the mansion burns down, some of the townspeople are killed, Wilbur gets struck by lightning, and Nancy ends up knocked up with what, one assumes, is another monster. The end.
No doubt about it, this is one lousy movie. Fans of Lovecraft should be advised that only the bones of his short story are here, and the rest is just all smoke and mirrors...but then again, there is always that groovy Lex Baxter score.
