Invitation to the Castle (French: L'Invitation au Château) is a 1947 satirical play by the French playwright Jean Anouilh. It was adapted in 1950 by Christopher Fry as Ring Round the Moon. The play concerns twins, a cold, manipulative playboy Hugo, and his sensitive brother Frédéric. Frédéric is madly in love with Diana, the spoiled daughter of a self-made millionaire. She herself wants Hugo, as his impenetrability teases her. In order to show to Frédéric that Diana is not worth his attentions, Hugo invites to a ball Isabelle, a lower-class dancer, whom he Pygmalion-like transforms into an aristocratic beauty.
