"Die, Monster, Die" is ostensibly based on H. P. Lovecraft's story "The Colour out of Space", but lacks the otherworldliness of Lovecraft's writings. Briefly, Reinhart (Nick Adams) is invited to the manor home of his British fiancée Susan (Suzan Farmer) by the girl's mother who, terrified by the strange things that are happening in the house, is slowly going insane. The local townspeople shun the family, Susan's unwelcoming wheel-chair-bound father (the great Boris Karloff) has a sinister secret, and there is something in the green and glowing greenhouse (and later in the basement). The film follows a similar trajectory to a number of Hammer horror offerings of the same era (the unwelcoming townies, the mysterious house, the imperilled girl, the suspicious deaths, the man with a secret, the climatic conflagration) and, despite its imaginative source material, has little new or interesting to offer. Nick Adams, who at the time was bouncing around the world trying to revive a flagging career (he co-starred in a Godzilla film in the same year) is OK as the rational, heroic fiancée, as is the Karloff, who delivers his lackluster lines in his iconic voice. Makeup and special effects are typical for the era (the gruesome 'melting' face scenes are quite well done) but overall, the movie is neither very entertaining nor very interesting. Without the Lovecraftian paranormal elements, the plot really makes no sense: there is nothing offered to counter Reinhart's 'logical' observations about radiation (which can't explain the madness and 'evil') beyond vague references to Karloff's dead father, whose portrait makes him look like someone wearing a devil costume at Halloween. I wonder if Adams and Karloff ever talked about the Japanese interpretation of Frankenstein's creature in another 1965 film in which Adams starred ("Frankenstein Conquers the World").

Adapted from the H.P. Lovecraft story The Colour Out of Space, Die, Monster, Die! opens with the arrival of American Stephen Reinhart (Nick Adams) at the English village of Arkham (a name that will no doubt be familiar to fans of Lovecraft). As is usually the case in such films, the locals are far from friendly, refusing to help him reach his destination, the Witley house, where his university sweetheart Susan (Suzan Farmer) lives with her mother Letitia (Freda Jackson) and father Nahum (an aged Boris Karloff).Eventually arriving at the Witley place on foot (having successfully avoided the man-trap by the gate), Stephen is confronted by Nahum, who tells him to leave. Susan, however, welcomes him with open arms and pointy boobs, clearly unperturbed by, or blissfully unaware of, their age difference (Adams, a decade older than his perky co-star, has a carefully concealed receding hairline and bags under his eyes). After Stephen is introduced to Letitia—who hides behind the veils that surround her bed and urges the young man to leave with her daughter—he begins to suspect that something very strange is happening at the Witley manor. And you know what? He's right!There are a couple of moments in Die, Monster, Die! that come very close to capturing the true horror and otherworldly dread of Lovecraft's writing: firstly, when our hero and heroine discover large mutated creatures caged in a greenhouse—nothing says Lovecraft more than tentacled beasties—and secondly, when Stephen locates the ominous green meteorite that has been causing the mutations, the glowing rock emitting a menacing hum that can only mean bad things. Sadly, the rest of the film is far less effective, plodding from one gloomy corridor, darkened room, or foggy exterior, to another as Stephen explores the house and its mist-shrouded grounds (narrowly avoiding Nahum, who is surprisingly nippy in his wheelchair).Director Daniel Haller would have another stab at bringing Lovecraft to the screen in 1970 with The Dunwich Horror, but with little success, while The Colour Out Of Space would be turned into another movie, The Curse, in 1987.

"The Colour Out of Space" by H.P. Lovecraft is turned into pretty much lousy movie. Titles "Die, Monster, Die!" and "Monster of Terror" are misleading as there are no monsters in this story. It is about mutations of plants and animals caused by meteor fallen into small isolated English town. There's too much idling although movie lasts just a little above an hour and even Boris Karloff didn't leave much of impression. Special effects are ridiculous. I understand that movie is made in 60's when they couldn't do much better than this, but it would be better if they simply left those shots out and based the movie more on building a tension, leaving our imagination to compensate for missing effects. This way it just ended up ridiculous and pretty much boring. From Karloff in Lovecraft's story I expected much much more than this.5/10

It was in the 1940's when mankind first discovered the Atomic bomb and many of the scientists working on it, hoped it would usher in a new world for mankind. In point of fact it did. The discovery brought forth the knowledge, the world could more easily destroy itself much easier than before, In the movies, like this horrific film called " Die Monster, Die " the new element called Uranium, did in fact bring a new beginning, it was called The Atomic age and the new element was global fear. In this story, an America has journeyed to England to visit his fiancé. One there, he is surprised to learn the town's people are terrified of the Witley family and wants nothing to do with them. Nevertheless, Stephen Reinhart (Nick Adams) seeks to discover the reason for the fear and is introduced to Mahum Witley (Boris Karloff), his fiancé Susan, Letitia (Freda Jackson) and their man servant, Merwyn (Terence de Marney). The family has an established, though terrifying history, but none so deadly as a monstrous secret glowing in their basement which is destined to infest the world. The movie is a horror of the sixties and has become a cult horror film. A fun monster movie to be sure and with the presence of the great Karloff, certain to be a classic. ****
