Gold Diggers of 1933 (1933) on Netflix

A wealthy composer rescues unemployed Broadway performers with a new play, but insists on remaining anonymous.

Chorus girls Polly, Carol and Trixie are ecstatic when they learn that Broadway producer Barney Hopkins is putting on a new show. He promises all of the girls parts in the new show and even hires their neighbor Brad Roberts, an unknown composer, to write some of the music. There's only one problem: he doesn't have the money to bankroll it all. That problem is solved when Brad turns out to be quite rich but he insists that he not perform. When opening night comes, the juvenile lead can't go on forcing Brad to take the stage. He's recognized of course and his upper crust family wants him to quit. When he refuses, they tell him to end his relationship with Polly or face having his income cut off. When Brad's snobbish brother Lawrence mistakes Carol for Polly, the girls decide to have a bit of fun and teach him a lesson.

Barney Hopkins is producing a new show on Broadway, but the day before it opens, the set and costumes are confiscated due to unpaid bills. Everybody is sitting in the street, and due to the Depression, there is no work for the three chorus girls Carol, Trixie and Polly. But they hear rumors that Barney is producing a new show. They talk to him, and he promises to give them work - when he finds a backer to produce the new show. Barney hears the tunes of the composer next door, Brad Roberts, Polly's friend. Brad joins them and agrees to back the show. On opening night Brad takes over for the juvenile lead, who is suffering from lumbago. Brad has been very publicity-shy, because he is a member of an upper-class wealthy Boston family. When his family hears what he is doing, his brother Lawrence and the family attorney Peabody come to New York, to end his relationship with Polly. But Lawrence mistakes Carol for Polly, who does not correct his mistake. Lawrence decides to separate Polly and Brad by getting Polly to fall in love with him. But soon Lawrence realizes that he is really in love with that chorus girl.
