Synopsis by Robert Firsching
The famed British horror trio of Christopher Lee, Peter Cushing, and director Terence Fisher brought John Lymington's sci-fi novel Night of the Big Heat to the screen in this slow-moving shocker. The plot concerns a small British island where alien protoplasm creatures are attempting to raise the temperatures to match those of their home planet. The result is a winter heat-wave so intense that most of the island's residents go up in flames. Lee and Cushing are among the few survivors able to battle the malignant extraterrestrial scourge. Fisher proves once again that his deliberately paced directorial style is better suited to Gothic horror than to what should be fast-moving sci-fi.
