Thirty-Day Princess (1934): Pre-Code comedy, Starring Sylvia Sidney and Cary Grant.

Marion Gering directed Thirty-Day Princess, a pre-Code comedy, starring Sylvia Sidney and Cary Grant.

The film was based on a story of the same name by Clarence Budington Kelland, in Ladies’ Home Journal in 1933, adapted by Sam Hellman and Edwin Justus Mayer, and written by Preston Sturges and Frank Partos.

Though Preston Sturges received writing credit, he wrote in his autobiography that “not much” of his work was used. 

On her way to New York to find backing for her impoverished country, the Ruritanian Kingdom of Taronia, Princess “Zizzi” Catterina (Sylvia Sidney) falls ill and must be quarantined for a month.

Financier Richard Gresham (Edward Arnold), who is planning to issue $50 million in Taronian bonds, hires unemployed lookalike actress Nancy Lane (Sidney again) to impersonate the princess. He offers her large bonus if she persuades the opponent of the financial transaction, newspaper publisher Porter Madison III (Cary Grant).
