• California Doubling: Despite being set in a microstate based on Monaco, which is located in southeastern France, the movie was filmed in Romania.
• Real-Life Relative: It's no wonder that Queen Isabella wants Duchess Natasha for a daughter-in-law, as the actresses playing them are mother and daughter in Real Life. This is even lampshaded when the Queen cheerfully tells Natasha "You remind me of myself at your age!"
