The Killer That Stalked New York (also known as Frightened City) is a 1950 American film noir directed by Earl McEvoy and starring Evelyn Keyes, Charles Korvin and William Bishop.

The film, shot on location and in a semi-documentary style, is about diamond smugglers who unknowingly start a smallpox outbreak in the New York City of 1947.

[1] Arriving at New York City's Pennsylvania Station after a trip to Cuba, Sheila Bennet (Evelyn Keyes), who is smuggling $50,000 worth of diamonds into the country, realizes she is being followed by the authorities.

Finding a growing number of smallpox victims, city officials decide to vaccinate everyone in New York to prevent an epidemic, but quickly run out of serum.

Evelyn Keyes, as the fugitive smallpox carrier, manifests great discomfort and distress, but she is no more than a melodramatic cipher in a loosely organized 'chase.'

William Bishop is blankly youthful as the physician and Charles Korvin is conventional as the lady's no-good husband who tries to give her the brush.
