When the COVID-19 pandemic and quarantine happened, production simply was halted for films and shows alike. Some shows managed to finish production of their most current season (For example, The Mandalorian is set to premiere it's second season on time this October on Disney+) while other shows had to adjust their last produced episodes as makeshift season finales. And some were in the middle of production for a yet-released season and now are just going to get back into the swing of things. Netflix's The Witcher is one major example, having just restarted production for season two in the United Kingdom. This was announced by joint Twitter posts by showrunner Lauren S. Hissrich and director Stephen Surjik with the behind-the-scenes photo below that links to that post:
The first season remains one of Netflix’s biggest success stories ratings wise. Based on the fantasy book saga (Which was previously adapted into a celebrated video games series), Henry Cavill is set to return as Geralt of Rivia along with the Anya Chalotra as Yennefer and Freya Allan as Ciri. Several new actors are joining the cast for the new season including Game of Thrones star Kristofer Hivju. Hivju was notable for being tested positive for the COVID-19 virus which partially led to production being shut down. He has been symptom free for months and hopefully the show can finish season two's production in time for a late-2020/early-2021 release on Netflix. Stay tuned!
