Netflix's The Witcher season 2 was confirmed in November 2019.
Vesemir is Geralt's mentor, a fellow witcher who trained Cavill's character in the witcher's keep of Kaer Morhen. He is the oldest remaining witcher, having survived a vicious attack from an angry mob of mages, and serves as a sort of father figure for Geralt and his Child Surprise, Ciri. His age and experience led him to become a fencing instructor for the School of the Wolf, where Geralt and other characters trained and gained their mutations. In the books, and seen in flashbacks in The Witcher III: Wild Hunt, explorable in VR by a fan.
Via a tweet from Netflix, Danish actor Kim Bodnia will be playing Vesemir, described as "the oldest and most experienced Witcher" on the Continent. Bodnia is most widely known for his role as detective Martin Rohde in the Scandinavian crime drama The Bridge; his other credits include roles on Killing Eve, Pusher, and Jon Stewart's Rosewater. Rumors had swirled that Mark Hamill (Star Wars) was in contention for the role, but that has been sufficiently disproven by Netflix's tweet.
Bodnia is not the only new face ing Netflix's hit fantasy series. a fearsome elf army appearing in season 2, who are a constant threat on the path to the witcher's keep.
To fans of the games, Vesemir was one of the most prominent characters missing from the show's first season, and Kaer Morhen is one of the most iconic locations in the series, serving as a player hub in Wild Hunt. Given that the notable success of the Netflix show has led to a huge spike in the Witcher game sales, the inclusion of such an iconic character and castle was inevitable.
