The Corsican Brothers; or, the Fatal Duel is a play by Dion Boucicault, first seen in 1852. It is a melodrama based on a French dramatization of the novel by Alexandre Dumas.
From 1850 Dion Boucicault was employed by the actor Charles Kean, who leased the Princess's Theatre, London, as the house dramatist. Boucicault, fluent in French, travelled to France to find plays he could adapt for the English stage; a result of this was The Corsican Brothers, adapted from the 1850 play Les Freres corses by Eugène Grangé and Xavier de Montépin.
The play, directed by Charles Kean, opened at the Princess's Theatre on 24 February 1852. Charles Kean played both of the brothers Fabien dei Franchi and Louis dei Franchi, and Alfred Wigan played Chateau-Renaud.
Act I and Act II are understood as taking place at the same time. Each of the brothers Fabien dei Franchi and Louis dei Franchi are able to sense if the other is in danger.
Act I
At his home in a castle in Corsica, Fabien dei Franchi becomes aware that his brother Louis, in Paris, is in danger. At the end of the act, after making peace between feuding local families, he has a vision of Louis' death in a duel.
Act II
The events leading to the duel are described. Louis has travelled to Paris to find Emilie de L'Esparre, with whom he has fallen in love. She has married, and he vows to accept the situation; her husband admires Louis' honesty in admitting the past affair, and asks him to protect her while he is away.
Chateau-Renaud, known as a womanizer and duellist, is pursuing Madame L'Esparre, and he challenges Louis to a duel. In the Forest of Fontainebleau, Louis is wounded in the ensuing sword fight; before he dies he tells his second that his brother will avenge his death.
Act III
Chateau-Renaud, with his friend and second Baron de Montgiron, try to flee the country, but their carriage crashes in the same clearing in the forest. Fabien dei Franchi appears: they think it is the ghost of Louis until he introduces himself. After a long sword fight, Chateau-Renaud is killed. At the end, the ghost of Louis appears once more.
George Henry Lewes wrote: "Charles Kean... seems now... settling down into the conviction that his talent does not lie in any Shakespearian sphere whatever, but in melodrames.... Charles Kean plays the two brothers; and you must see him before you will believe how well and quietly he plays them; preserving a gentlemany demeanour, a drawingroom manner very difficult to assume on the stage, if one may judge from its rarity, which intensifies the passion of the part, and gives it a terrible reality.... The duel between him and Wigan was a masterpiece on both sides; the Bois de Boulogne itself has scarcely seen a duel more real or more exciting...."
