Here are the characters/cast of DUP's upcoming dark play, The Duchess of Malfi. (Source)
The Duchess. The protagonist, sister to Ferdinand and the Cardinal. At the beginning, she is a widow in the prime of her life. Though her brothers take every precaution to keep her from marriage, she secretly marries her steward Antonio. Her brothers arrange to have her strangled. She is described as having a sweet countenance and noble virtue. Witty and clever, she can keep up with her brothers’ banter. She also has a tenderness and warmth that they lack. She has three children, two sons and a daughter by Antonio.
Antonio Bologna. Antonio has recently returned from France, full of scorn for the Italian courtiers whom he sees as more corrupt than the French. Antonio is the steward of the Duchess of Malfi's palace. He accepts the Duchess' proposal of marriage because of her disposition rather than her beauty. Her marrying beneath herself is a problem, however, and their marriage has to remain a secret, and Antonio shares neither her title nor her money. Bosola accidentally kills him.
Daniel de Bosola. A former servant of the Cardinal, now returned from a sentence in the galleys for murder. Publicly rejected by his previous employer the Cardinal, he is sent by the twin brother of the Duchess to spy on the her. Bosola is involved in the murder of the Duchess, her children, Cariola, Antonio, the Cardinal, Ferdinand, and another servant.
The Cardinal. The brother to the Duchess and Ferdinand. A corrupt, icy official in the Roman Catholic Church who keeps a mistress—not uncharacteristic of the time—he has arranged a spy (Bosola) to spy upon his sister - all this on the quiet, however, leaving others ignorant of his plotting. Of remorse, love, loyalty, or even greed, he knows nothing, and his reasons for hating his sister are a mystery.
Ferdinand. The Duke of Calabria and twin brother of the Duchess. Unlike his rational brother the Cardinal, Ferdinand is given to fits of rage and violent outbursts disproportionate to the perceived offence. He gradually loses his sanity—he believes he is a wolf and digs up graves—but, upon seeing his dead sister, has the grace to regret hiring Bosola to kill her.
Julia. The Cardinal's mistress. She dies at the Cardinal's hands from a poisoned Bible.
