The British drama Merlin has been booked for a fifth season by the BBC, and the fourth season will return this fall. The fourth season will be broadcast on the Syfy channel in the United States in early 2012. It is reported that the fourth season of Merlin is currently being filmed in Wales and France. At the 2011 San Diego Comic-Con, the two executive producers of the show, Johnny Capps and Julian Murphy, jointly announced that Merlin has been booked for a fifth season by the BBC. Johnny Capps revealed that the new season of Merlin will give the show's writers more creative space, and the fourth season of Merlin will consist of two adventure stories. Merlin wants to ensure that Arthur can fulfill the great mission given to him by history and become the legendary eternal king. The fourth season of Merlin has all the original cast members returning. In addition, three new actors have joined, Nathaniel Parker, Phil Davis and Gemma Jones. Among them, Nathaniel Parker will play "Agravaine", the uncle of "Arthur" played by Bradley James, and the latter two will be guest stars. Merlin is adapted from the story of King Arthur and the magician Merlin. Merlin in this play is no longer a white-haired old man, but a young boy. The story will focus on how the young Merlin recognizes his mission and turns enemies into friends with Prince Arthur to save the magic world. After the show was broadcast, it was deeply loved by the British. Among them, the ratings of the third season increased by nearly 12% compared with the second season.
