Unearthly Stranger1963

Horror Vault's take

When scientists involved in a classified space research program begin dying under bizarre circumstances, their colleagues find themselves gripped by mounting dread and suspicion. Attention turns to one researcher's enigmatic wife, whose strange habits and unnerving calm suggest she may be something far removed from ordinary humanity. This lean British chiller trades flashy effects for creeping psychological unease, letting atmosphere and ambiguity do the heavy lifting. The result is a quietly unsettling portrait of paranoia where the most familiar setting — a marriage — becomes the most alien place of all.
