Charles' mother gave them a plot in Hyères, for which first Mies van der Rohe and then Le Corbusier was asked to design a house.

In fact he preferred men, as Marie-Laure discovered early in their married life, when she happened to come to his bedroom one afternoon and found him in bed with his good-looking gym instructor.

[5] Charles financed Man Ray's film Les Mystères du Château de Dé (1929), which centers around Villa Noailles in Hyères.

He also financed Jean Cocteau's film Le Sang d'un Poète (1930) and Luis Buñuel and Salvador Dalí's L'Âge d'Or (1930).

Charles and his wife appeared in Les Mystères du Château de Dé as well as Le Sang d'un Poète.
