This clever horror movie deals about a couple (Ray Lovelock, Cristina Galbo) afflicted by stalking, vicious Zombies (Jose Lifante, Fernando Hilbeck,Joaquin Hinojosa and many others) relieved by ultrasonic radiation caused by agricultural experimentation. Meanwhile a grumpy Police Inspector (Arthur Kennedy) is investigating the strange events.
Gory, gruesome , and ghastly cannibal feast in which the stumbling flesh-eating stiffs are reanimated by means of radioactive waves and can be only destroyed by fire. Unrelenting shock-feast laced with touches of ecological denounce. Army of Zombies appearance roaming the countryside , graveyard and some people besieged inside a hospital deliver the goods , enough to be interesting. Jorge Grau's first great success is compelling directed with startling visual content . This frightening movie is plenty of thrills, chills, body-count executed by the eerie Zombies and photographed in glimmer color with lurid images and phenomenal results. This is a classic Zombie film where the intrigue,tension, suspense appears threatening and lurking in the foggy outdoors and every room, and corridors from a hospital. At the time considered the plus ultra of disturbing movie is less stomach-churning by nowadays's standards, yet its fundamental power to thrill remains undiminished. Agreeable performance by Cristina Gabo who made various Giallo and Horror movies as ¨The boarding school¨ , ¨What have you done to Solange¨, ¨The killer must strike again¨. This genuinely frightening story with correct utilization of images-shock is well photographed by Francisco Sempere in location of England : Manchester, Derbyshires , Italy : Cinecitta studios and Madrid . Creepie and eerie musical score by Sorgini. Jorge Grau who also made another good terror film titled 'Ceremonia Sangrienta' creates a rare Zombie thriller that manages to be both scary and skilfully made, deserving its cult status . Rating: Good, this is one more imaginative horror pictures in which the camera stalks in sinister style . An average budget horror movie that still packs a punch for those who like to be terrorized out their wits.
