Watch Night of the Big Heat

Night of the Big Heat is a 1967 British science fiction horror film directed by Terence Fisher and starring Christopher Lee, Patrick Allen, and Peter Cushing. The plot is based on John Lymington's 1959 novel Heat Wave, which is a traditional sci-fi narrative that involves an impending alien invasion of Earth. The story takes place on a small, remote island off the coast of England, where the weather has taken a dramatic turn for the worse, with the temperature rising to unbearable levels. When a scientist named Godfrey Hanson (Patrick Allen) arrives on the island to investigate the strange weather conditions, he finds that the local population is in a state of panic.

Hanson soon discovers that the source of the excessive heat is not natural but caused by an alien race that has taken refuge deep within the Earth's core. The aliens are using their advanced technology to create a microclimate on Earth that will allow them to survive on the surface.

As the heat continues to rise, tensions on the island also increase, and fear and paranoia begin to take hold. A local hotel owner (Christopher Lee) and his wife (Sarah Lawson) become trapped in the middle of the chaos as people start to act irrationally and turn on one another.

As the temperature reaches lethal levels, Hanson and the hotel owner must unite to find a way to stop the alien invasion before it's too late.

The film is notable for its strong cast, with Christopher Lee delivering a particularly memorable performance as the menacing hotel owner, who's willing to do whatever it takes to survive. Patrick Allen is convincing in his role as the level-headed scientist trying to save the island, while Peter Cushing makes a brief appearance as another scientist who is struggling to understand what's going on.

The visual effects are impressive for their time, especially considering the relatively low budget of the film. The island's parched landscape and the red glow of the sky create a post-apocalyptic feel that is appropriately unsettling.

Night of the Big Heat is a suspenseful and entertaining film that will keep viewers on the edge of their seats. It's a classic British sci-fi horror movie that is well worth watching, especially for fans of the genre.
