A couple months ago, we showed you a first look at Guillermo del Toro’s DreamWorks Animation series, Trollhunters. The show “features a tale of two fantastical worlds set to 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 will impact their lives forever.”

Today, the first casting has been announced for the show, and it’s got some strong names lined up. According to a press release, Anton Yelchin will voice Jim, Kelsey Grammer will voice “’Blinky,’ a kind-hearted troll who befriends Jim; and Ron Perlman provides the voice of ‘Bular,’ a sinister troll who targets Jim and his friends for battle.” Hopefully, we’ll get a look at how this is all coming together in the near future.

Here’s the press release. Trollhunters hits Netflix this December.
