Paid to Love (movie, 1927)

An American banker goes to a small Balkan country looking to invest his bank's money and shore up the country's weak economy in order to maximize the return on their investment. Towards that end he befriends the country's king and they come up with a scheme to get the Crown Prince married, a prospect not particularly appealing to the Crown Prince--until he sees the beautiful cabaret dancer the pair has picked for him to marry.
