Table of Contents

“Attack of the Crab Monsters” is a film horror/sci-fi of 1957 directed by Roger Corman. The plot follows a group of scientists who travel to an island in the Pacific to investigate the disappearance of another group of researchers. Upon arriving on the island, they discover that their colleagues have been killed by giant mutant crabs, the result of a series of nuclear tests conducted in the area.

The film was produced on a very small budget and using rather rudimentary special effects, but it has become a cult film thanks to its style “B-movie” and to its fantastical and bizarre plot. Critics rated it as a film both funny and scary, which exploits the clichés of the genre in a creative way.

Ultimately, “Attack of the Crab Monsters” is a must-see movie for lovers of horror and sci-fi movies from the 1950s, but also for those looking for a fun and undemanding cinematic experience.




The plot of “Attack of the Crab Monsters” follows a group of scientists who go to the island of Deros to investigate the disappearance of a group of colleagues who were conducting research on the mutation of life forms following nuclear tests.

Once on the island, the protagonists discover that their colleagues have been killed by huge mutant crabs, which have developed a kind of intelligence and the ability to blend into their surroundings. Furthermore, crabs appear to be able to absorb the knowledge of the people they kill, thus becoming increasingly dangerous and unpredictable.

The survivors will therefore have to try to survive the attack of the crabs and to find a way to defeat them before they can destroy the whole island and put the entire planet at risk.

The plot, although simple and full of clichés, is accompanied by a good dose of tension and fear, thanks to the gloomy and claustrophobic atmosphere that permeates the entire film.

Here are some of the main characters featured in “Attack of the Crab Monsters”:

Martha Hunter: Dale’s girlfriend and also a scientist who participates in the expedition to the island of Deros.

Dr. Karl Weigand: He is the leader of the expedition and the genetic mutation expert who conducted the nuclear tests on the island. It is played by actor Russell Johnson who later became famous for his role as the ‘Professor’ in the TV series ‘Gilligan’s Island’.

Hank Chapman: is the pilot of the plane that transports the shipment to the island and gets stuck there along with the others.

Despite these limitations, the film was moderately successful at the box office and has earned its place in cinematic history as one of the classics”monster movie” of the 1950s. The production also contributed to the career of Roger Corman, who would later become one of the most influential directors in American cinema, mainly for his role in the creation of a series of horror films and sci-fi low-budget that contributed to the birth of indie movies.

“Attack of the Crab Monsters” is a classic example of a 1950s “monster movie”, a subgenre of science fiction and horror cinema that was characterized by the presence of giant monsters that threatened humanity. The film has many of the typical elements of this genre, such as the predictable plot, formulaic characters and simple but evocative special effects.
