One of my sci-fi/horror/fantasy reviews written 50 years ago: Directed by Jerry Hopper for Paramount release, "The Atomic City" stars Gene Barry (in his movie debut), Milburn Stone, Lydia Clarke and Nancy Gates.
A straight science fiction-espionage thriller that emphasizes suspense rather than gadgetry, as physicist Gene's son is kidnapped by enemy agents. The Los Alamos setting was topical at the time, and proves to be still relevant.
Gene Barry's magnetism on screen served him in good stead, not as a movie star but as the lead in successful series I enjoyed like "Bat Masterson" and "Burke's Law", quite different genres but both made his own as a smooth performer -the sort of easy, comfortable personality as an actor that Perry Como exuded as a singer/host.
