Earlier this month, Henry Cavill, who plays Geralt of Rivia in Netflix's The Witcher, told his followers on Instagram that the show's second season is about to enter pre-production, and that he'll provide more updates soon. So, with the show's second season entering pre-production, Netflix is looking into finding new cast members for their hit show, and one of the potential new cast members played one of the most popular characters on HBO's Game of Thrones. \n \nKristofer Hivju, who played Tormund Giantsbane in Game of Thrones, might be joining The Witcher's cast for season two, as Stephen Surjik, who has been scouting filming locations for the show's second season, shared a post on his Instagram page that has since been deleted, where he tagged Kristofer Hivju along with Henry Cavill and Anya Chalotra (Yennefer of Vengerberg). It's worth noting that Surjik and Hivju have never worked together before. \n \nAfter being tagged in the now-deleted post, Hivju followed three different accounts dedicated to the Netflix series, which has led many to believe that he'll join the show's cast for season two. Also, sources who are closely involved with the show have said that they've heard the ex-Game of Thrones star's name before as a potential cast member, so it seems pretty likely that he's joining the show for season two. \n \nhttps:\/\/www.youtube.com\/watch?v=ndl1W4ltcmg \n \nSince being linked to season two of The Witcher, fans of the book series, which the show is based on, have predicted that Hivju will play Nivellen, who looks like a bear because of a curse. \n \nAnother major star who could be joining the cast of The Witcher for season two is Mark Hamill, who might land the role of Vesemir. Admittedly, the man who played Luke Skywalker doesn't know much about The Witcher, but he's interested in joining the cast. \n \nWhen responding to the fan campaign, Lauren Hissrich, the showrunner, said that she hasn't been in contact with Hamill, but being that she's a massive Star Wars fan, she'd love to have him play Vesemir. \n"Mark has always been of interest to me and interest to the project," said The Witcher's showrunner. "We have not contacted his agent yet because we’re not casting the role quite yet, but that being said, I am loving what’s happening on the internet." \nAll eight episodes of The Witcher are available now on Netflix, and if you haven't seen season one yet, you'll have plenty of time to catch up as the show's second season won't be released until 2021.
