BBC's adaption of Philip Pullman’s His Dark Materials trilogy is moving full steam ahead. It was announced today that The King’s Speech director Tom Hooper has officially boarded the eight-part series. Also set to join the forthcoming series are Logan's Dafne Keen and Hamilton's Lin-Manuel Miranda.

According to Deadline, Keen is in talks to play the role of Lyra, an orphan who lives in a parallel universe. Meanwhile, Miranda is in talks for the role of balloonist and adventurer Lee Scoresby. Keen, of course, is coming off a star-making role as Laura, aka X-23, in Fox's Logan, while Miranda is coming off the Broadway hit Hamilton, which he created and starred in.

BBC One's eight-part series will span Pullman’s His Dark Materials trilogy, which includes The Golden Compass (also known as Northern Lights), The Subtle Knife and The Amber Spyglass. The project was initially ordered by the BBC back in 2015, with the network hiring Jack Thorne to pen the series shortly thereafter. BBC Worldwide is entertaining offers from the likes of Apple and Netflix for both U.S. and global rights. Production on the series is expected to kick off relatively soon in Wales, with more casting news to be revealed in the coming weeks.

Pullman’s Northern Lights was previously adapted for the big screen back in 2007 as The Golden Compass and starred Nicole Kidman, Daniel Craig, and Eva Green. That film, which was written and directed by Chris Weitz, was critically panned and only made $372 million worldwide on a $180 million production budget.

As of now, a premiere date for His Dark Materials is unknown.
