All the King's Horses (1935)

King Rudolf XIV of Langenstein, is too busy to make love to his wife, Queen Elaine of Langenstein, and good Queen Elaine is upset royally about it. She departs the palace and tells him she will not return until he learns how to make love to her,and, as a parting shot, until he also shaves off his ancestral beard. Too much of one thing and not enough of another. As often happens in Langenstein, an Hollywood actor, Carlo Rocco, who is an exact double for the king, shows up, and the King naturally hires him to take his place while the King goes to Vienna to learn how to live and make love. (Vienna?). Carlo not only is a good actor and capable replacement for, ere long, the Queen falls madly in love with a man she thinks is her husband. Plus, he has learned how to sing. (Pre-code film.)
