The Man in the Iron Mask

In this version, the twins' ages are swapped: Philippe is the firstborn and rightful king, who had been spirited away at birth and raised with no knowledge of his true identity in a plot by Cardinal Mazarin to manipulate Louis before his own death. Colbert and D'Artagnan plot to replace Louis (who is an ineffective king more interested in dancing and pleasure than the welfare of France) with Philippe, and in the process bring down the corrupt finance minister Fouquet, who has Embezzlement from the national treasury. Louis is repulsed by his own wife and makes repeated advances on Louise, who is in turn repulsed by him yet falls in love with Philippe.
