To say we're excited for the new BBC adaptation of 'His Dark Materials' is something of an understatement.

Philip Pullman's trilogy is one of our favourites and the 2007 film of the first book 'Northern Lights' (titled 'The Golden Compass') didn't quite do it justice. However, the BBB One production - which has started filming in Cardiff in recent weeks - is shaping up to be a lot better, and the good news is that a second series has reportedy already been green-lit.

Pullman's story follows the fortunes of young orphan Lyra and her friend Will in an earth-like fantasy world, but one where everyone has a daemon - a representation of their soul - in animal form outside of their body. The books deal with themes of philosophy, theology and more, while also being a seriously entertaining story.

The cast of the series, meanwhile - which is rumoured to be one of the most expensive British TV productions ever - includes Lin-Manuel Miranda as explorer Lee Scoresby, James McAvoy as the mysterious Lord Asriel and Dafne Keen as Lyra.

Deadline says that the BBC have ordered another 8 episodes, although it's not yet known if the second series will encompass any of the second book, 'The Subtle Knife'. Either way, it's something to look forward to.
