When a group of isolated people in the Greek mountains set off a cave explosion, they are menaced by an invisible shrieking dinosaur that had been buried for eons.As it happens, director José Antonio Nieves Conde was fairly prolific from the 1940s through the 1970s. Unfortunately, he was mostly prolific in Spain, and therefore little known in the United States. I wonder what other gems he has to offer and how easy they would be to track down...This film also features the debut of Ingrid Pitt, which has to be worth something. This is a cheap horror film (invisible dinosaurs are about as inexpensive as it gets), but having Pitt in there makes it quite important in retrospect...

The Sound of Horror is a mid-60s Spanish horror film set in Greece. Some men are looking for buried treasure after obtaining both halves of a secret treasure map which leads them to an old cave. After blowing up portions of the cave, they discover a mummy, a skeleton, and some semi-petrified dinosaur eggs. One of the eggs hatches to produce a transparent dinosaur-like monster which terrorizes the men and the ladies. Not content to stay in its cave, the monster roams around and attacks the cabin where the people are staying.The suspense factor is actually not bad, I'll give the suspense factor a six. The special effects are awful though. There are a couple of brief flashes of the monster (it looks like a plastic Godzilla model picked up at a discount toy store) and stop-motion effects to show the footprints of the monster walking through the flour. Finally, the monster shrieks sound like a person going "AAAAAHEEEAAAAAHH" and nothing more. Anyway the monster gets one star.The stunningly beautiful Soledad Miranda, however, gets a solid eight just for the Greek dancing and standing around looking so pretty. Overall, not bad, I give it a four.

What could possibly be more frightening than a face-shredding, chest-gouging prehistoric monster? Well, how about one with a particularly bloodcurdling scream? Or even better...howzabout one which, in addition to all of the above, and due to its complete camouflaging ability, IS TOTALLY INVISIBLE?!?! Anyway, it is just such a see-through monstrosity that menaces the characters of the 1965 Spanish film "Sound of Horror." In the picture, a trio of aging treasure hunters breaks into a long-lost cavern in the wilds of modern-day Greece, thus releasing the petrified egg of the unseeable whatsit. And very soon after, the freshly hatched, ravening beastie begins to kill off their helpers and traps the trio, their driver, the niece of one of the men (future Jess Franco muse Soledad Miranda, almost unrecognizable here) and the girlfriend of one of the others (future Hammer vampiress Ingrid Pitt, absolutely unrecognizable here) in a lonely old house in the valley. But how to fight an enemy that you simply cannot see?"Sound of Horror" is a relatively obscure little picture, and that is something of a shame. The film is actually very well put together, and it is quite remarkable how much suspense director J.A. Nieves Conde is able to generate utilizing only his actors' reactions, sound effects, and the moody strings of composer Luis de Pablo. Though we never get to see the film's monster--except for some split-second images in what I gather is refracted light, and once in the midst of smoke and flames--its hideous wailings (the film IS well named) and squishy footfalls are enough to elicit shivers. The reactions of the film's characters are quite realistic, too; when they hear the creature for the first time, these war-toughened men bolt as quickly as they possibly can! The picture features some fairly effective gross-out moments as the monster inflicts its mayhem, despite the fact that the movie was filmed in B&W. Actually, it is a pity that it could not have been shot in color, as the countryside outside Madrid (standing in for Greece) would have thus been nicely captured. And speaking of color, this viewer could not help wishing that our harried band in the film could just do what Jonny Quest and Co. did when battling "The Invisible Monster" from that TV episode (also from 1965); namely, drop some paint on the darn thing so we could get a good solid look at it! Still, despite all, this is a surprisingly involving little film, with some nice twists and surprises toward the end, as that darn monster proves itself to be stunningly resilient. And how can you dislike any film in which two characters, facing their demise, agree that the most important things in life are dancing, flowers, books and music? How many horror films have extolled the virtues of these four things? I love it! Oh...as for this DVD itself, it is yet another crummy-looking one from those indolent underachievers at Alpha Video. This is certainly a film that deserves a loving restoration, and much more than the Alpha treatment!

I liked this movie although its not really scary at all, potentially it should have been. In some ways this movie reminded me a bit of the Kurt Russel version of the Thing. It has some of the same "what the heck is going on?" vibe that gradually overwhelms the characters. I really liked the originality of the screaming yet invisible monster. You hear it coming as it stomp stomp stomps along, then it makes these weird grunting noises and finally screams like a banshee...cool! There are some ideas here that could have really pushed this movie over the top...unfortunately the direction is really pretty weak and the cast brings nothing to their roles with the exception of hottie horror honey Ingrid Pitt, looking all sexy and sassy in her teased up hair and short shorts.It still manages to be interesting despite the shortcomings. One wonders though what might have been with more skillful direction, a little more money, and a couple of well known stars. Still, I'm not really complaining, I was digging this offbeat movie anyhow. I give it a six for the nice writing and Ingrid Pitt!! Lots of blood for an early sixties movie.
