If you’re a horror fan you may be rolling your eyes at the idea of being terrified by radio shows. But I guarantee that if you listen to these productions in a darkened room or while driving down a road in the middle of nowhere at midnight you will likely look over your shoulder.

Once upon a screen... 
Interesting! As a Lovecraft fan, I was unaware that there had been a version of “The Dunwich Horror” produced so early. I thought the Dean Stockwell version (1970) was the first. Live and learn.
Other earlier Lovecraft film titles include EDGAR ALLAN POE’S THE HAUNTED PALACE, with the plot mostly based on his short novel “The Case of Charles Dexter Ward”, DIE, MONSTER DIE!, based on “The Colour Out of Space”, and THE SHUTTERED ROOM based on the Lovecraft/Derleth story. Another film I think was heavily influenced by Lovecraft was THE CURSE OF THE DEMON, although I cannot find any other mention of this by anyone else. The other above films were from the 60’s, yet CURSE came from the year 1957.
With apologies to Aurora, I’ll continue with our discussion here, where it began. I don’t find your argument regarding “Curse of the Demon” very convincing. Lovecraft never wrote about a monster resembling the demon shown at the end of that movie, and said demon, as you may know, was inserted against the express wishes of director Jacques Tourneur and writer Charles Bennett. The monster was put in at the insistence of producer Hal E. Chester, who so far as I know had no other connection to H.P Lovecraft. The only argument you present in favor of this connection is that the monster is large, by which argument King Kong and Mighty Joe Young are now “Lovecraftian” monsters.
