Syfy has ordered up a fourth season of international hit Merlin.
Syfy said Merlin performed well, averaging 1.93 million total viewers, up 12%, in its third season and rising 7% in the 18-34 demographic. The show is from FremantleMedia Enterprises, produced by Shine TV.
The fourth season will be broadcast in the United Kingdom this fall and on Syfy in the U.S. in early 2012. Known as The Adventures of Merlin outside the U.K. and U.S., the fantasy series is broadcast in 183 countries, according to FremantleMedia Enterprises.
The fourth season will see Camelot on the brink of a Golden Age as the familiar blend of magic, mystery and action adventure returns. With Morgana now a dangerous outcast, Merlin must use all his power to ensure Arthur fulfils his destiny as the Once and Future King.
Colin Morgan returns as Merlin alongside Bradley James as Prince Arthur and Angel Coulby as Gwen, and stars as Katie McGrath as Morgana. Broken after Morgana's betrayal, Anthony Head also reprises his role as King Uther and Richard Wilson continues to support and advise Merlin as Gaius.
New to the fourth season is Nathaniel Parker (The Inspector Lynley Mysteries) as Agravaine. Other guest stars already confirmed for season four include Gemma Jones (Bridget Jones) as the mysterious Cailleach and Phil Davis (Sherlock) as "The Gleeman," an old world Circus-master with a dark and sinister secret.
Legendary actor John Hurt continues to provide the voice of the Great Dragon.
