as a collector of vintage sci-fi movies from the 20"s through the 60"s i have found many use a cookie cutter mentality with no new imagination,that does not mean they are not good movies, but the story often is not very original,been done before,etc., that said, i like the story of the sound of horror even at the risk of being ridiculed,*** (my co-workers broke into tears of laughter when i told them i liked a movie about an invisible prehistoric dinosaur)***these same individuals looked me straight in the eye and told me how believable it was to them that a family could feed and pet a brontosaurus in Jurassic park!*** give me a break!*** anyway,that being said, i find sound of horror to be very unique in imagination and concept,the film was obviously a low budget production,yet,it has more intense suspense than some million dollar movies of later vintage. the only available copy at this writing is just a "fair" print quality wise,and the movie was Spanish origin with English dubbing,** still, i recommend this movie to serious "vintage" sci-fi collectors, its very different and thats what makes it stand out among the crowd.*** it really is kind of creepy,*** even today,*** turn the lights out when you watch it!***creepy soundtrack highlights it also! ****
