I recently watched the Spanish giallo 🇪🇸 No One Heard the Scream (1973) on Shudder. The storyline follows a female escort who opens her apartment door and sees her neighbor dropping a woman's body down the elevator shaft. He forces her to be his accomplice, and a unique relationship forms.
This film is directed by Eloy de la Iglesia (El Pico 1 & 2) and stars Carmen Sevilla (Glass Ceiling), Vicente Parra (The Cannibal Man), Maria Asquerino (Dying of Laughter), and Antonio Casas (The Good, the Bad and the Ugly).
This is one of those films where unexpected events keep unfolding. It has very creative twists and turns and is well-written. The acting by the two main characters is solid. The background sound effects and overall soundtrack create the perfect atmosphere. The elevator shaft sequence is particularly well done. There's a fun boat scene that could have been executed better but was still entertaining. All the ending scenes at the camp gave me anxiety, especially once some of the characters revealed their true intentions. The film also has a smart conclusion.
In conclusion, No One Heard the Scream is a worthwhile Spanish giallo that I would recommend to fans of the genre. I would score this a 7/10 and recommend seeing it at least once.
