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.
