Once Upon a Honeymoon is a 1942 romantic comedy/drama starring Cary Grant, Ginger Rogers, and Walter Slezak, directed by Leo McCarey, and released by RKO Radio Pictures. It was nominated for the Academy Award for Best Sound Recording (Stephen Dunn).

In the days leading up to World War II, Katie O'Hara (Ginger Rogers), an American burlesque performer masquerading as American socialite "Katherine Butt-Smith", pronounced byüt-smith, is about to marry Austrian Baron Von Luber (Walter Slezak). Foreign correspondent Pat O'Toole (Cary Grant) suspects Von Luber of being a Nazi sympathizer and tries unsuccessfully to get information from Katie by deceit, but is warned off by Von Luber.

Undaunted, O'Toole follows the couple to Prague, where O'Hara and Von Luber marry. After the annexation of Czechoslovakia by Germany, the Von Lubers travel to Warsaw, where the baron sells arms to Polish General Borelski (Albert Bassermann). O'Toole warns the General of the dangers of trusting in Von Luber. When the General tries the weapons he finds out he has been sold duds and plans to notify his government. When the Germans invade Poland, the weapons prove to be defective. Von Luber is arrested on suspicion but warns his young bride not to worry because no one will be able to bear witness against him. Soon after, the General is assassinated along with a young Nazi the Baron has chosen to sacrifice. While the Baron is in jail O'Hara and O'Toole decide to flee the country. However, O'Hara has given her passport to her Jewish maid Anna, so that the woman and her two children may escape the country. O'Hara and O'Toole escape to Norway, Holland and Belgium (all of which subsequently fall to the Germans) and then to Paris all at the hand of Von Luber.
