A scorching picture from 1967, Night of the Big Heat is a sweat-inducing shocker based on the 1957 novel from John Lymington. The remote island of Fara is experiencing a stifling heat wave in the middle of winter, causing life, as the locals know it, to come to a halt. Tensions rise as the heat increases plus a high-pitched tone of unknown origin is incinerating the villagers. 

Directed by Hammer favourite, Terence Fisher and starring Peter Cushing and Christopher Lee alongside chisel jawed Patrick Allen, Night of the Big Heat is sizzling British sci-fi at its most intense.
