Peter Cushing, Edward Judd and Carole Gray are three people that travel to a small island off the coast of Scotland to investigate a mysterious death and find themselves fighting for their lives as well as the lives of everyone on the island.
A local scientist who was working on a cure for cancer accidentally created a new life form in the shape of bone eating silicate monsters that seem to be indestructible.
The sounds these monsters make when eating human bone works very well and it always gave me nightmares when I was younger. The lead actors are all top notch and add a very high degree of realism to the proceedings.
I am still awaiting the Blu-ray release of the film here in the US. It is lone overdue. Anyway, this film is a perfect movie for Halloween, and is a damn near perfect horror movie.
There are some very scary scenes in this film and some will not be soon forgotten, especially when Cushing gets his hand cut off to save his life. RECOMMENDED!
