Fantomas Unleashed

Fantomas Unleashed continues the story of the masked criminal Fantômas, who resurfaces a year after Commissioner Juve and the journalist Fandor last failed to capture him. This time Fantômas abducts the scientist Professor Marchand, apparently intending to force him to build a weapon of enormous power. Realising that Marchand's assistant, Professor Lefebvre, is likely to be the next target, Fandor disguises himself as Lefebvre to catch the villain. The plan misfires, and Fandor, Juve and Hélène all end up in Fantômas's hands, leaving them to work out how to escape. The film is the second entry in a trilogy, following Fantomas (1964) and preceding Fantomas vs. Scotland Yard (1967), and it is one of several films André Hunebelle directed, among them The Three Musketeers (1953) and Sous le signe de Monte-Cristo (1968).

Jean Marais plays multiple roles, appearing as Fantômas, Fandor, Lefebvre and the Marquis de Rostelli, while Louis de Funès returns as Commissaire Juve and Mylène Demongeot as Hélène. The screenplay was written by Jean Halain and Pierre Foucaud, with Alain Poiré and Paul Cadéac producing. The film runs 105 minutes and blends adventure, comedy, crime and fantasy, with a credited cast of 32.
