Did You Know?

The film had never been picked up by a German distributor during its initial release phase. Only in 2012 the film was released by Austrian label Shock Entertainment, who even created a German dubbing (in 70s style). In 2014 the film was released officially for the first time in Germany (by Mad Dimension).See more »

From the director of Tombs of the Blind Dead comes WHEN THE SCREAMING STOPS!, 16 April 2000
Author: B.M. from FL

This 1976 movie retitled in the mid-80's When the Screaming Stops, was distributed by those fine folks over at Lightning Video. The cover proclaimed "Includes Red Flash Warning to Prepare You For Explicit Horror". This I might add was quite a novel idea, being that the story isn't terribly original.

The back of the box goes as this--

You survived HALLOWEEN. You made it through NIGHT OF THE LIVING DEAD. You've come a long way, but are you ready for WHEN THE SCREAMING STOPS?

In a small village near the Rhine River young women begin to meet a mysterious and brutal death. Each of the young girl's bodies is found torn apart...and missing their hearts. Fearing that the beast may strike next at the School for Young Women, an experienced hunter is hired to find and destroy the ruthless animal.

But the town and the hunter are deceived - this is no beast that craves human hearts, but a most deceptive, alluring and mysterious creature. It cautiously awaits its next unsuspecting victim.

You won't be able to move from your seat - WHEN THE SCREAMING STOPS!

I can assure you, after viewing this film it is no where near as scary as what they make it out to be. As a matter of fact it wasn't really scary at all. Where the film lacks in scares it more than makes up for in the gore department, and the interesting idea of the red flashes before the murders, which I thought was very cool.

Honestly I can only recommend this movie to a horror completist because this is just about as obscure they get. The ending came right out of left field, and made absolutely no sense whatsoever. Personally I liked Amando De Ossorio's Tombs of the Blind Dead much more than this film, though it had some nice touches and a certain outdated charm to it.
