Fox's immediate follow-up to its successful early-talkie western In Old Arizona was 1929's Romance of the Rio Grande. The story focuses on the Alvarez family of Mexico, specifically fabulously wealthy Don Fernando. Intending to bequeath his vast fortune and estate to his long-estranged grandson Pancho, Don Fernando must contend with his ne'er-do-well nephew Juan.
