Trollhunters has added three to its cast for its second season. Mark Hamill, Lena Headey, and David Bradley will all be featured on the series when it returns.

Netflix revealed more about the additions in a press release. Check that out below.

“Mark Hamill, Lena Headey and David Bradley have joined the second season of Netflix’s critically-acclaimed series DreamWorks Trollhunters, from Guillermo del Toro. They join an already star-studded cast from season one that includes Kelsey Grammer in his Emmy-winning role as Blinky, Ron Perlman (Bular), Steven Yeun (Steve), Anjelica Huston (Queen Ursurna), Jonathan Hyde (Strickler), Amy Landecker (Barbara) and Charlie Saxton (Toby). The late Anton Yelchin is featured in the lead role as Jim Lake, Jr. and completed recording through season 2.

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.

Hamill voices the unknown older brother to a member of the Trollhunting team but has pledged his loyalty to the evil Gunmar.

Headey plays an extremely powerful and evil sorceress who must be stopped at all costs, while Bradley voices a mysterious figure known to have great magical powers — but the Trollhunters find he’s not the mystical wizard they expected.

Season two, premiering later this year, picks up with Jim entering the Darklands by himself, leaving his best friends and fellow Trollhunters, Toby and Claire, behind.

The Netflix original series premiered on Dec 23, 2016, with the first-ever 26-episode debut. In February, del Toro announced a second season of 13 episodes would debut in late 2017.

Earlier this spring, DreamWorks Trollhunters lead the Creative Arts Daytime Emmys with six wins, more than any other program, including writing for an animated program (Marc Guggenheim), directing (Rodrigo Blaas, del Toro), casting (Ania O’Hare, Mary Hildalgo) and a voice acting win for Grammer.

DreamWorks Trollhunters is created and executive produced by del Toro with Marc Guggenheim (Arrow, Legends of Tomorrow), Rodrigo Blaas (Alma) and Chad Hammes (Dragons: Race to the Edge) and Christina Steinberg (Rise of the Guardians) serving as executive producers. Dan Hageman (The Lego Movie, Ninjago) and Kevin Hageman (The Lego Movie, Ninjago) serve as co-executive producers.”
