The BBC have released a 30-second launch trailer for the fourth series of Merlin; a show I tend to enjoy, but keep wishing would be better. There are great elements and occasionally things come together to produce a wonderful episode, mainly because the cast have good rapport, but it keeps getting stuck having to cater for seven-year-olds. Still, it's been getting progressively darker since series 2, and this trailer continues that trend. There's nothing very special about this promo (the editing and music is awfully clichéd), but I'm sure fans are squeeing so hard they're not even reading these words.
Series 4 will guest-star James Callis (Battlestar Galactica) as an old pupil of Gaius' called Borden, Lindsay Duncan (Rome) as Queen Annis, Gemma Jones (Spooks), Phil Davies (Whitechapel), and Nathaniel Parker as Arthur's uncle Agravaine.
MERLIN returns to BBC1 in October. A fifth series has already been commissioned by the BBC, and the producers are apparently developing a feature-film.
