The first of the "Dr. Mabuse" films not directed by Fritz Lang, the French/German/Italian Return of Dr. Mabuse stars Wolfgang Preiss in the title role. Supposedly dead and buried, Mabuse returns to his criminal activities, once more using hypnotized flunkeys to carry out his dirty work. While the doc's longtime foe Inspector Lohmann (Gert Froebe) probes and prods in his usual methodical fashion, hotshot American detective Lex Barker and dauntless girl reporter Daliah Lavi take the more direct approach to weed out Mabuse. This time around, the diabolical doctor wants to sabotage a nuclear reactor, then take over the world (he never does anything by halves). Return of Dr. Mabuse was released in Europe as Im Stahlnetz des Dr. Mabuse, Le Retour Du Docteur Mabuse and FBI Contro Dr. Mabuse; in some American cities, it was shipped out as Phantom Fiend.

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. Hal Erickson, Rovi
