Thirty-Day Princess (1934)

Synopsis
A European princess heads for New York in order to see if the U. S. will back her country's bond issue. Unfortunately, she is afflicted with the mumps and ordered to bed. This is an ill turn for the banker planning to issue the bonds for if the princess reneges upon her public engagements, the deal could fall through and he will lose a huge commission. Thinking quickly, he starts looking for a look-alike. He soon discovers an impoverished actress who fits the bill. Trouble brews when a prominent and somewhat xenophobic newspaper publisher gets wind of the entire scam. ~ Sandra Brennan, All Movie Guide
