Harry Revier

He scored notoriety of a sort with the infamous "Poverty Row" serial The Lost City (1935) featuring William "Stage" Boyd, an actor known for his alcoholism who died shortly after the film’s completion (in one famous incident, he was arrested in a drunken escapade and a newspaper story covering it the next day mistakenly published a photo of actor William Boyd, later to become famous as "Hopalong Cassidy"; the mistake put a screeching halt to his at the time rising career)--the film is regarded many many aficionados as "the worst serial ever made".

In 1936 Revier discovered some ethnographic footage of flagellant monks shot in New Mexico several years previously and built a racy feature around it, with star Marie DeForrest presented in a nude crucifixion scene.

The film—the first produced by exploitation-film legend Kroger Babb, who marketed it as an "educational" picture—was a somewhat cheesy tale of early-teen and pre-teen girls being married off to elderly men, a long-standing practice in some of the more backward areas of the American South.

Through the use of creative editing Revier converted the 1939 sci-fi serial Buck Rogers into an Atomic Age, Cold War context.
