Thirty Day Princess (1934): Pre-Code Cmedy, Starring Sylvia Sidney, Cary Grant and Edward Arnold

Marion Gering directed Thirty Day Princess, a pre-Code comedy, starring Sylvia Sidney in a dual role, Cary Grant in a thankless part, and Edward Arnold as second banana.

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.

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

Financier Richard Gresham (Edward Arnold), who’s 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 influences the chief opponent of the financial transaction, newspaper publisher Porter Madison III (Cary Grant).

Preston Sturges received credit for the screenplay, but not much of his work was used.

Sporadically entertaining, the movie’s lighter tone was a change of pace for Sidney, who’s better known for her grim roles in Fritz Lang’s early American movies.

Released on May 18, 1934, Thirty-Day Princess was ultimately a minor affair that did little to further Cary Grant’s career.
