According to an official press release, Hamill will play the older brother of one of the Trollhunting team's members. The role will be a villainous one as Hamill's unnamed character has pledged his loyalty to antagonist Gunmar. While probably most well-known for his work on Star Wars, Hamill is also famous for his voice work, having played the Joker in Batman: The Animated Series.

Netflix didn't give much information on Headey's role, only describing her as "an extremely powerful and evil sorceress who must be stopped at all costs." She currently plays Cersei Lannister on HBO's Game of Thrones.

Hamill and Headey will join the likes of the late Anton Yelchin (Jim Lake, Jr.), Kelsey Grammer (Blinky), Ron Perlman (Bular), Steven Yeun (Steve), Anjelica Huston (Queen Ursurna), Jonathan Hyde (Strickler), Amy Landecker (Barbara) and Charlie Saxton (Toby).

The official synopsis for Trollhunters reads:

DreamWorks Trollhunters features a tale of two fantastical worlds that collide in an epic saga. Set in the fictional suburb of Arcadia, our unlikely hero, Jim, and his two best friends make a startling discovery that beneath their hometown lies a hidden battle between good trolls and bad, the outcome of which impacts their lives forever.

Season two of the hit series will have Jim leave behind his best friends, Toby and Claire, in order to venture into the Darklands alone.
