HBO and BBC One have begun production on the third and final season of His Dark Materials. The eight-episode third season is based on The Amber Spyglass, the final novel in Philip Pullman's award-winning trilogy with production taking place at Wolf Studios Wales stages and on location throughout Wales and England.

Adapting Philip Pullman's award-winning trilogy of the same name, which is considered a modern masterpiece of imaginative fiction, His Dark Materials series follows Lyra (Dafne Keen), a seemingly ordinary but brave young woman from another world.

Season three will see Will (Amir Wilson), the bearer of The Subtle Knife, and Lyra (Dafne Keen), the prophesied child, travel through multiple worlds to find and protect each other. As well as Amir Wilson and Dafne Keen, James McAvoy and Ruth Wilson will be returning for the final season with Adewale Akinnuoye-Agbaje (Suicide Squad, Lost) and Kobna Holdbrook-Smith (ZackSnyder's Justice League, Mary Poppins Returns) joining the cast.

Executive Producer Dan McCulloch says: “The moment we started season one of His Dark Materials, we had mapped out all three novels to know the direction in which where we were heading. Every detail and character within this incredible work of fiction has been analysed and discussed for four years now, and to finally arrive in the many worlds of ‘The Amber Spyglass' is thrilling.”
