The Return of the Musketeers is a 1989 film adaptation loosely based on the novel Twenty Years After (1845) by Alexandre Dumas. It is the third Musketeers film directed by Richard Lester, following 1973's The Three Musketeers and 1974's The Four Musketeers. Like the other two films, the screenplay was written by George MacDonald Fraser. The character of Mordaunt, Milady de Winter's son in the original novel, is replaced by Milady's daughter, called Justine de Winter. Several cast members from the first two reprised their roles in this one. Jean-Pierre Cassel, who played Louis XIII in the original films, has a cameo appearance as Cyrano de Bergerac. While filming in September 1988, character actor Roy Kinnear died following an on-camera accident in which he fell off a horse. His role was completed by using a stand-in, filmed from the rear, and dubbed-in lines from a voice artist. Plot Twenty years after the events of The Four Musketeers, Cardinal Mazarin has imprisoned the Duke of Beaufort. Mazarin hires d'Artagnan to bring together Athos, Porthos, and Aramis, to work for him. Porthos accepts, but Athos and Aramis decline. By this time, Athos has a son named Raoul. Milady de Winter's daughter, Justine, captures and questions the executioner that the musketeers hired to kill her mother. After finding out that "Comte de la Fere" hired him, she kills him. Raoul happens upon the aftermath of this event and chases after Justine, who is disguised as a priest. After a swordfight, when he discovers who she really is and her plan, Raoul leaves and tells d'Artagnan, Porthos, and Athos that Justine wants to kill them. Comte de Rochefort is unable to prevent Beaufort from escaping from his prison, and he is subsequently arrested by Mazarin. Mazarin sends d'Artagnan and Porthos after Beaufort, but Beaufort escapes them due to interference from Athos and Aramis, who are working for Beaufort. This starts a fight amongst the Musketeers, in which d'Artagnan slices Aramis' hand. Aramis breaks his sword and rides away. d'Artagnan and Porthos are fired by Mazarin for not catching Beaufort. Rochefort, who has survived his near-fatal clash with d'Artagnan in the previous film and has gone into hiding, finds Justine and tells her the names of d'Artagnan, Porthos, and Aramis, revealing to her that the Comte de la Fere is Athos.
