Well I was shocked anyway. I was shocked to discover that the film Haunted Palace was based on Lovecraft's "The Case of Charles Dexter Ward". The Dexter story is a fave' of mine, as it's one of the audio books I recorded a while ago. I hadn't realised any films had been made that used it as a source. It's a 1963 film starring Vincent Price. I have got to get hold of this film!
