Premise: 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.
Hypothesis: Wallace Beery was P. T. Barnum in a 1930 film by Sidney Franklin.
