A scientist’s thoughts materialize as an army of invisible brain-shaped monsters (complete with spinal-cord tails!) who terrorize an American military base in this nightmarish chiller, directed by Arthur Crabtree (HORRORS OF THE BLACK MUSEUM). This outstanding sci-fi/horror hybrid is a special effects bonanza, and a high-water mark in British genre filmmaking.
