"Boudoir Diplomat" was, of course, a 1930s euphemism for a wealthy man who slept around. Ian Keith plays Baron Valmi, who uses his charms to rise to the top of the aristocracy ladder. The Baron is required to romance a series of eligible high-born ladies, but he's careful never to become emotionally involved. And then the lovely Helene (Betty Compson) enters his life. Based on a play by Rudolph Lothar and Fritz Gottwald, Boudoir Diplomat was directed by Mal St. Clair, one of the best of the silent era's Lubitsch wanna-bes.
