BBC One's Merlin bows out after five series Over the years, the programme has included an array of guest stars which has included Michelle Ryan, Emilia Fox, Mackenzie Crook, Adrian Lester, Warwick Davis and Miriam Margoyles. Johnny Capps, who co-created the show with Julian Murphy, said: "This is the series where the storylines truly reach their apex. We always felt the story of the legend was best told across five series, leading to a spectacular finale that draws on the best-known elements of this much-loved story and brings to a conclusion the battle for Camelot. Capps confirmed earlier this summer that he and Murphy were planning to make feature-length films out of the series. We're hopefully going to do a trilogy - three movies. We will focus on them when we finish season five," he told Digital Spy. One idea we've been playing around with is to reboot the whole series [for the films]. We would go back in time and start the story again and show different parts that you didn't see in the series. The other idea is to do a continuation, but we haven't decided yet. BBC One controller Danny Cohen said: "I admire the creators' decision to end Merlin on a high, but also know that we will miss it in the BBC One schedule. We have ambitious plans for new drama in the Saturday evening slot in 2013.
