On February 12 of 2020, Netflix entered the first day of filming for the second season of Henry Cavill’s The Witcher. We know very little about season two at this time, and many new cast members are expected to be announced (for the roles of Vesemir, Eskel, Lambert, Francesca, Philippa, Dijkstra and more), but we have now learned details of season two’s first location shoot in the Surrey Hills.
The Witcher crew have been filming at the Surrey Redlands, near Dorking. We are now able to confirm that the rumor is true. The Witcher crew have gathered in Surrey for two back-to-back night-shoots on the 12th and 13th, filming in the forest with smoke machines and massive lighting rigs.
