Rose of Washington Square

Rose of Washington Square is a 1939 American musical drama film, featuring the already well-known popular song with the same title. Set in 1920s New York City, the film focuses on singer Rose Sargent and her turbulent relationship with con artist Barton DeWitt Clinton, whose criminal activities threaten her professional success in the Ziegfeld Follies.
Although the names of the principal characters were changed, the plot was obviously inspired by vaudeville entertainer Fanny Brice's career and marriage to gambler Nicky Arnstein (both the film's title song and "My Man" were closely associated with Brice), and Brice sued 20th Century Fox for $750,000. The studio settled out of court for an undisclosed amount.
Written by Nunnally Johnson (who co-produced with Darryl F. Zanuck) and directed by Gregory Ratoff, it stars Alice Faye, Tyrone Power and Al Jolson, with a supporting cast that includes William Frawley, Joyce Compton, Hobart Cavanaugh, Moroni Olsen, Charles Lane, and Louis Prima.
Plot.
Ted Cotter (Al Jolson), a successful Broadway minstrel performer, spots Rose Sargent (Alice Faye) performing in a vaudeville amateur night. He immediately takes a personal and professional interest in her, helping her career along as she joins the famed Ziegfeld Follies and begins to achieve stardom.
Rose does not recognize Ted's love for her, falling instead for Bart Clinton (Tyrone Power), a gambler and con man. Bart's nefarious activities get him arrested, and after Ted puts up his bail, Bart skips town. Rose pines away for him, until one night, when Bart goes to the Follies and hears her tearful rendition of the song "My Man", he realizes the error of his ways and sets out to make things right. As Bart is sent away for a 5-year prison sentence, Rose says "I'll be waiting, darling!"
