BBC and HBO joined forces in 2019 to create His Dark Materials, an eight-part series which is an adaptation of Philip Pullman's fantasy book trilogy of the same name (you would have likely heard of the 2007 film, The Golden Compass, which is based on The Northern Lights.) The second season landed on our screens this year, and saw a few unexpected faces in its new cast, including Andrew Scott and Phoebe Waller-Bridge and Game of Thrones star Bella Ramsey.
