Prince of Foxes (1949)

Andrea Orsini (Tyrone Power) is a dutiful employee of the powerful Italian nobleman Cesare Borgia (Orson Welles). When Orsini is sent to case a region Borgia intends to seize, overseen by the upstanding Count Verano (Felix Aylmer), Orsini begins to doubt his work and question Borgia's scheming ways. Once Orsini falls for Verano's pretty wife Camilla (Wanda Hendrix), whom Borgia also has his sights on, Orsini realizes he must finally stand up to his boss, no matter the cost.
