I wonder what RFK Jr. would have to say about The Killer That Stalked New York, now that he threatens to put his anti-vax quackery into effect. It's a taut little thriller about a smallpox epidemic, in which the heroes are the governmental and medical officials who race against time to vaccinate 8 million people against the disease while its carrier moves among them. The carrier is Sheila Bennet (Evelyn Keyes), who has been to Cuba to retrieve some diamonds that her boyfriend, Matt Krane (Charles Korvin), wants to fence. Somewhere in her journey, she started to get sick, and by the time she arrives in New York City, she's really not feeling so well. Trying to dodge the Treasury agent (Barry Kelley) who's on her tail, she plays hide-and-seek around the city, and when she discovers her boyfriend is double-crossing her, she gets even more furtive. Several people will die from direct contact with her, and others will become carriers before her pursuers, including the doctor (William Bishop) who treated her without knowing the real nature of her disease, finally track her down. A voiceover (Reed Hadley) keeps hyping the urgency of the situation, but it's really not necessary -- Earl McEvoy's crisp pacing and the effective location shooting by Joseph F. Biroc supply enough intensity and reality. There are some nice surprises among the cast, including Dorothy Malone as a nurse and Jim Backus as a club owner, both of them pre-stardom.
