Sex-kittenish advertising artist Gilda Farrell (Hopkins) has a meet-cute with fellow American bohemians Tom Chambers (March), a playwright, and George Curtis (Cooper), a painter, aboard a European train. The three form an unusual ménage à trois: they’ll share a Parisian loft; she’ll serve as muse and critic for the struggling artists; and everybody’s happy…so long as they can manage to not have sex. A surprisingly frank adaptation of Noël Coward’s play (though altered almost beyond recognition by screenwriter Ben Hecht).
