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. However, Johnny Capps revealed on the 18th of March 2011 that the show has been increased to its original 13 episodes, opening with a two-parter. Filming started in mid-March 2011.
