Production on the second series was halted in March at the onset of the coronavirus pandemic.
Rasmussen revealed on Instagram this week that he had to exit the series, calling it a “heartbreaking” decision and wishing everyone luck on the production of season two.
Deadline reports that Swiss actor Eidenbez, whose previous credits include historical drama Victoria and a role in The Favourite, starring Olivia Colman and Emma Stone, will now take on the role.
Other actors joining season two of The Witcher include Game of Thrones star Kristofer Hiviu (as Nivellen), Agnes Bjorn (as Vereena), Peaky Blinders star Paul Bullion (as Lambert), and Killing Eve’s Kim Bodnia (as Vesemir, Geralt and Eskel’s mentor).
