Series 4



 14 Days Left Series 4 of Merlin will air in autumn 2011. Its air date is rumoured to be October the 8th for the UK. The series was originally cut to ten episodes from the previous series' 13 due to financial issues. However, Johnny Capps revealed on 18 March 2011 that the show has been increased to its original 13 weekly episodes, opening with a two-parter. Filming started in mid-March 2011 in Cardiff, Wales and Pierrefonds, France. This season is said to be darker and more mature 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. The offical tagline for the fourth series is: The Darkest Hour Is Just Before The Dawn. At the SDCC Merlin Panel, it was confirmed that due to the show's increasing popularity, a fifth season has been comissioned by the BBC.
