Netflix is incredibly happy with the success of The Witcher television show. That should already be clear, given that Netflix greenlit a second season of The Witcher before the first season aired. Apparently greenlighting a second season wasn't enough, however. Netflix wants more of The Witcher and it's not willing to wait until the show gets around to a third or fourth season. Today Netflix announced that it would be making a Witcher anime film alongside the ongoing live-action TV show.
In an announcement made over Twitter, Netflix confirmed that an anime production named The Witcher: Nightmare of the Wolf is now in the works. It's unclear whether The Witcher: Nightmare of the Wolf will be based on the book series or if it will be original material. The only context provided for the animated film's story is that it includes "a new threat facing the Continent." There's definitely plenty of source material in Andrzej Sapkowski's Witcher books and dozens of short stories.
There's also a question as to whether The Witcher: Nightmare of the Wolf will be a tie-in to The Witcher television show. According to the announcement, the new animated film will be produced by The Witcher writer/producers Lauren S. Hissrich and Beau DeMayo. Their direct involvement could mean that The Witcher: Nightmare of the Wolf will tie in with The Witcher TV show's story.
The only other information provided about The Witcher: Nightmare of the Wolf is the studio that will be handling the animation. Studio Mir is based in Korea and has an impressive list of shows that it's worked on. The studio's first project was Avatar: The Legend of Korra, as the studio's executive director had previously worked on Avatar: The Last Airbender. The studio's most recent project has been Voltron: Legendary Defender, which was also developed for Netflix.
Netflix doesn't have any further information, like runtime or release date, to share as of yet regarding The Witcher: Nightmare of the Wolf. What's important is that the film exists and is in production. Also important is that Netflix is showing very clearly how invested it is in The Witcher going forward. Just one season has aired and already Netflix is funding an anime film based on the show. It hints that this may be just the start of Netflix's plans for The Witcher franchise.
The Witcher: Nightmare of the Wolf is coming to Netflix, but has no current release window.
