It was directed by Josef von Sternberg and stars Marlene Dietrich, Clive Brook, Anna May Wong and Warner Oland.

"Boule de Suif", translated variously as "Dumpling", "Butterball", "Ball of Fat", or "Ball of Lard", is a short story by the late-19th-century French writer Guy de Maupassant, first published on 15/16 April 1880. It is arguably his most famous short story and is the title story for his collection on the Franco-Prussian War, titled Boule de Suif et Autres Contes de la Guerre.
