The British actor replaces Pierce Brosnan, who played the Centaur character in Percy Jackson & the Olympians: Lightning Thief. Chiron is in charge of Camp Half-Blood, where demigods like the title character receive their training.
This is the second character from Percy Jackson & the Olympians: Lightning Thief who has been recast in the past week, after we reported that Nathan Fillion is replacing Dylan Neal as Hermes. Logan Lerman, Alexandra Daddario, Brandon T. Jackson, and Jake Abel are returning for the sequel.
Thor Freudenthal is directing Percy Jackson: Sea of Monsters from a script by Scott Alexander and Larry Karaszewski, which is adapted from Rick Riordan's novel series. No production schedule was given for Percy Jackson: Sea of Monsters.
