BBC/HBO's new fantasy series His Dark Materials is a lavish adaptation of the book trilogy by Philip Pullman, and boasts an impressive cast that includes James McAvoy, Ruth Wilson, Dafne Keen and Lin-Manuel Miranda. The series is set an a parallel universe where people's souls exist outside of their bodies in the form of animal companions called daemons, who shapeshift throughout childhood before eventually settling into a final form. A young orphan, Lyra Belacqua, is embroiled into a sprawling mystery that could forever upset the balance of power in this world.

Season 2 of His Dark Materials completed filming before season 1 even premiered, and the biggest piece of casting for the second season is Amir Wilson as Will Parry, the deuteragonist of the novels. Will is introduced in the second book, The Subtle Knife, and finds his way from our world into Lyra's world. Also joining the cast in season 2 is Andrew Scott as Will's father, John Parry (also known as Stanislaus Grumman or Jopari).
