Rupert Everett and Matthew McNulty are joining the Season 3 cast of The Musketeers, the BBC announced.

Everett will play Philippe Achille -- Marquis de Feron, the corrupt governor of Paris, head of the Red Guard and illegitimate brother to Louis XIII. McNulty will play the vicious criminal Lucien Grimaud.

"Both men go up against the Musketeers and bring chaos and sedition to the monarchy and Paris," the British broadcaster said in a news release.

The actors join the returning cast of Luke Pasqualino as d'Artagnan, Tom Burke as Athos, Howard Charles as Porthos, Santiago Cabrera as Aramis, Hugo Speer as Captain Treville, Ryan Gage as King Louis, Alexandra Dowling as Queen Anne and Tamla Kari as Constance.

"I'm very excited to be joining the cast of The Musketeers for the new series. I love the show and am really looking forward to working with the team," Everett said in a statement.

Hilary Martin, head of BBC Drama North, added: "The third series of The Musketeers promises to be an ambitious and electric piece of drama. We are thrilled our lead writers Simon Ashford and Simon Allen's fantastic scripts have attracted such exceptionally high-caliber actors to join the Musketeers on their exciting journey through war-torn and politically turbulent 17th-century Paris."
