Series 4



Series 4
Series 4 of Merlin will air in autumn 2011. Its air date is not yet known. The series was originally cut to ten episodes from the previous series' 13 due to financial issues. It was deemed better to reduce the length of the series and maintain the quality rather than staying with 13 episodes but having to reduce the budget and therefor the quality for each. It was also originally rumored to air in early 2012, later than its usual slot in autumn so that it wouldn't clash with Autumn half of Doctor Who Series 6 running in the same period. However, Johnny Capps revealed on 18 March 2011 that the show has been increased to its original 13 episodes, opening with a two-parter. Filming started in mid-March 2011. Block 1 at Pierrefonds finished May 20th and the cast and crew should return to France for Block 2, starting June 20th and continuing until June 24th. This season is said to be darker than the rest, with the other three having a few violent scenes, and this one having much more. Most characters will show a darker side to their personality. Colin Morgan has revealed that Merlin series 4 will air in September or October 2011.
