His Dark Materials season 3 is the third and final series in the BBC and HBO adaptation of Philip Pullman's His Dark Materials (opens in new tab) trilogy. 

Fittingly, the third series is based on The Amber Spyglass (opens in new tab), the final novel in the trilogy. The BBC and HBO production will once again be produced by Bad Wolf and Amit Gupta will lead as director of the opening two episodes; he will then be followed by Charles Martin and Weronika Tofilska.

Speaking about the latest installment, Bad Wolf Founder and Executive Producer Jane Tranter said: “The Amber Spyglass is the most gloriously complex of Philip Pullman’s novels to adapt for TV, but with our world-class creative team in Cardiff, no challenge is too daunting. 

"This season is both an epic adventure and a story about love and truth. Jack, Francesca, and Amelia’s scripts capture the brilliance of Philip’s worlds and we are joined by our much-loved existing cast and some exceptional talent new to the series.”

Here's what we know about His Dark Materials season 3 so far...

What is the plot of His Dark Materials season 3?

Season 3 picks up where we left off, where Lord Asriel called upon the angels to help him wage a war, and Mrs Coulter abducted her daughter Lyra to take her to "safety" back in their own world. This prompts Will to try and find Lyra to save her from her mother.

According to the BBC: "Season 3 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."
