The Bafta Award-winning BBC and HBO co-production, based on Philip Pullman’s trilogy, has entered production on its final season.

Lyra and Will are back on the scene for 'His Dark Materials' final season, the filming of which got underway this week.

Starring Dafne Keen ('Logan') and Amir Wilson ('The Kid Who Would Be King') the third and final season will see their characters close out the epic conclusion to the young adult franchise, based on Philip Pullman's fantasy trilogy.

The first set image from season three has been released, showing Dafne and Amir posing with the first clapper-board of the series - but it's dated a month ago, back in May. Production takes place in the sound stages at Wolf Studios in Wales and on location throughout Wales and England.

'The Amber Spyglass' will follow on from the climactic ending of season two, which saw Lyra get back into the clutches of her estranged mother, Mrs Coulter (played by 'Luther' actor Ruth Wilson), after seeing her friend Roger appear to her. Lord Asriel ('X-Men' star James McAvoy) also reared his head again, calling upon the angels to help him wage a war against the Kingdom of Heaven. We also saw Lin-Manuel Miranda's Lee Scoresby and his daemon Hester bite the bullet.

According to the BBC, here's how 'His Dark Materials' season three will kick off: "Series three opens with Lyra unconscious, having been given a sleeping draught by her mother, as Will, still carrying the Subtle Knife, continues his quest to find her. Will is tracked down by two angels - Balthamos and Baruch - who wish to take him to join Lord Asriel’s campaign against The Authority with Commander Ogunwe. But Will is not the only one after Lyra, with Father President MacPhail continuing his mission to destroy the child of the prophecy, employing the help of his most committed follower, Father Gomez.

"Meanwhile Oxford physicist Mary Malone (played by Irish actor Simone Kirby) reaches another parallel world - that of the Mulefa, a strange animal-like species. They tell her of a cataclysmic phenomenon in their world."

The BBC has announced a number of new cast members that will join the final showdown of the fantasy drama. Adewale Akinnuoye-Agbaje (Mr. Eko from 'LOST') stars as Commander Ogunwe, with Jamie Ward ('The Durrells) as Father Gomez. Kobna Holdbrook-Smith ('Zack Snyder’s Justice League'), Simon Harrison ('Everest'), and Chipo Chung ('Into The Badlands') will play the rebel angels Balthamos, Baruch and Xaphania, with Amber Fitzgerald-Woolf starring in the role of Ama.

Expect more 'His Dark Materials' final season updates in the coming months.
