Don Quixote (Cervantes): Tall, thin man in his late forties, he is an actor, playwright, and would-be knight. He is a romantic—some sane crazy—and has a vision of a far better and nobler world, where knights and chivalry rule the day.
Sancho (The Manservant): Older than Don Quixote, Sancho is short and squat. He has served Quixote/Cervantes for many years and is devoted to him, even with all his idiosyncracies.
Captain of the Inquisition
Aldonza: A serving woman and a part-time prostitute at the inn, Aldonza is rough on the exterior, but has a gentle heart inside and yearns to believe what Don Quixote tells her. Quixote falls in loves with her and insists her name is Dulcinea and that she is a beautiful, gentle woman.
The Innkeeper (The Governor): A large and powerful man, he is kind as the Innkeeper, but as the Governor is the leader of the inmate society in the prison.
Dr. Carrasco (The Duke): As the character of the Duke he sidekick to the Governor; however, when he plays Dr. Carrasco, he is Antonia's fiancé. He thinks Don Quixote mad and insists that he come home and be treated for his malady.
Antonia: Quixote's niece and Dr. Carrasco's fiancée.
Pedro: The head muleteer, Pedro is a mean and vicious man, leading an attack on Aldonza.
