Synopsis by Hal Erickson
Though director Fritz Lang, who started the "Dr. Mabuse" ball rolling back in 1922, had washed his hands of the series in the early 1960s, the Mabuse films kept popping up throughout the decade. This one stars Lex Barker as a New York detective investigating the criminal activities of the supposedly deceased evil genius Mabuse (Wolfgang Preiss). The bad doctor wants to get his paws on "Operation X", a serum that makes people invisible. Karin Dor, playing the daughter of the facially disfigured inventor of Operation X, is kidnaped by Mabuse and becomes a human bargaining chip. The Invisible Dr. Mabuse (original German title: Die Unsichtbaren Krallen des Dr. Mabuse) was released in some markets as The Invisible Horror.
