The Counterfeiters of Paris

Le cave se rebiffe is a 1961 French comedy film directed by Gilles Grangier, written by Michel Audiard and starring Jean Gabin, Bernard Blier and Martine Carol.

Éric, a crooked secondhand car dealer in Paris, is having an affair with the flirtatious Solange, whose unemployed husband Robert is a skilled printer and engraver.

With two crooked friends, Charles and Lucas, he discusses the idea that they could use the ineffectual Robert to run off some counterfeit banknotes.

In fact, they decide, they need to call in an expert and the best man for the job is Ferdinand, living in retirement in Venezuela.

Ferdinand agrees to help but on condition he has half the profits, which sets the other three working on a plot to reduce his take.
