The Moderns.

Nick Hart is a struggling American artist who lives amongst the expatriate community in 1920s Paris. He spends most of his time drinking and socializing in local café's and pestering gallery owner Libby Valentin to sell his paintings. He becomes involved in a plot by wealthy art patroness Nathalie de Ville to forge three paintings. This leads to several run-ins with American rubber magnate Bertram Stone, who happens to be married to Hart's ex-wife Rachel.
