You know, Amicus Films was responsible for another hidden gem called The City of the Dead (1960) also known as Horror Hotel. Today it has achieved classic status. It was distinguished in part by a highly unusual score -- unusual for Douglas Gamley -- that included Gregorian chants. The film is worth watching and the score is worth pursuing, especially if you like The House That Dripped Blood.
Horror Hotel is a wonderful film - John Llewellyn Moxey directed it. Very atmospheric and a wonderful Gamley score.
Indeed it is a wonderful film, expertly and stylishly directed by Moxey his first time out. I've studied his set-ups in the TV movies he directed. The film is a lifelong favorite of mine.
$25 burns a hole in my pocket for the score on CD.
