In the film Juve teams up with journalist Fandor, also played by Marais, trying to catch Fantômas but never quite succeeding.

It is the first film of a trilogy,[2] and Fantômas became extremely successful in Europe, the Soviet Union and Japan.

Mylène Demongeot plays "Hélène Gurn", the girlfriend of "Jérôme Fandor", Fantômas' arch enemy.

Commissaire Juve, as played by Louis de Funès, becomes a comedic character, much unlike his literary counterpart.

He can impersonate anyone using an array of masks and can create endless confusion by constantly changing his appearance.
