A Lady's Morals is a 1930 American Pre-Code film offering a highly fictionalized account of singer Jenny Lind. The movie features opera diva Grace Moore as Lind, Reginald Denny as a lover, and Wallace Beery as P. T. Barnum; Beery would play Barnum again four years later in "The Mighty Barnum". The film contains some fine opera arias by Moore and was directed by Sidney Franklin.

I basically just rewrote the text that was provided to keep it correct/accurate. It might be difficult to the system because I inferred that Jenny Lind was an Opera singer by the info stating the actress that played her role in the movie was an opera diva.
