New Moon is a 1930 black-and-white American, pre-Code romantic/drama/melodrama musical film version of the operetta The New Moon, with music by Sigmund Romberg and book and lyrics by Oscar Hammerstein II and others. The original stage version premiered on Broadway in 1928. A second adaptation, also titled New Moon, was released in 1940. To avoid confusion with the later version, the film was shown on television as Parisian Belle.
