• I know this movie since twenty seven years now, and I have never forgotten it. The first time I watched it, it gave me the creeps. I am sure this film, as SHADOW OF THE CAT, inspired some episodes, in the scheme and atmosphere of THE AVENGERS TV show, where the famous couple Diana Rigg and Patrick McNee had to investigate at the boundaries of the science fiction. That's the best Arthur Crabtree's film, with maybe HORRORS AT THE BLACK MUSEUM. I won't repeat the topic, already explained in the other comments. But, please, don't miss this one. But I also admit that this story is not typically British, it could have been American as well.
