Merlin Season Four will reportedly first make its U.K. premiere this fall, with 13 episodes. Based on previous seasons, Syfy is likely to air the show next spring.
The series drew an estimated 1.49 million viewers per week for Syfy, and 1.87 million for the season finale. Overall this was an improvement of 17 percent from the second season.
Merlin stars Colin Morgan as Merlin, Bradley James as Prince Arthur, and Angel Coulby as Gwen. Katie McGrath, Anthony Head and Richard Wilson will also return for the new season, along with John Hurt as the voice of the Great Dragon.
Nathaniel Parker will join the series in the role of Agravaine.
Starz’s version of the Camelot story, meanwhile, will end at just one season. Whether is was the show’s good but not great ratings or an inability to strike deals with the key players, the premium cable channel has cancelled Camelot, starring Joseph Fiennes.
