The script was co-authored by Groucho Marx and his dry wit is often present. This was his first on-screen credit for a film not involving the Marx Brothers, and his only film screenplay.
This film was released soon after the abdication of King Edward VIII so he could marry American divorcee Wallis Simpson. A contemporary reviewer noted the casting of Fernand Gravey and his resemblance to the Duke of Windsor. Groucho Marx, who co-wrote the script, later remarked, "any similarity between our story and the love affair between the King of England and Mrs. Simpson was intentional".
Although never officially acknowledged, this film bears a striking resemblance in both concept and plot to the 1957 Laurence Olivier/Marilyn Monroe vehicle The Prince and the Showgirl.
According to the AFI Catalog entry for this film, the ex-king's limo actually belonged to actress Constance Bennett.
