One of the first big fights you see on Netflix's The Witcher happens between Henry Cavill's Geralt and Emma Appleton's Renfri, and that clash was sorted and choreographed by Wolfgang Stegemann, who Cavill had worked with on Mission Impossible: Fallout. But Stegemann wasn't the full-time Witcher series stunt coordinator. No, that was Vladimir Furdik - aka Game of Thrones' Night King!

Netflix's Behind the Scenes podcast revealed how Furdik envisioned Geralt as a fighter as well as how he constructed the actual first confrontation on the series: Geralt's slaying of the Kikimora.Though the Kikimora battle was never described in the Andrzej Sapkowski Witcher story "The Lesser Evil," which is what the premiere episode adapts, showrunner Lauren Schmidt Hissrich thought "What's a better way to introduce [Geralt] than having him killing a monster when you first find him?""In the books we actually never see him kill the Kikimora," she explained to host Brandon Jenkins. "He actually arrives in Blaviken with the Kikimora's head on his donkey. So we never get to see him kill it.""We spent almost one month on this fight," Furdik said. "I thought that [Geralt] should be fighter who can already predict, three seconds ahead, when he's going to kill someone else. When he fights somebody he can already predict what they're doing. So his fight should look like very comfortable, kind of like ballet."In his gym, Furdik prepared for the fight, taking into consideration that "the Kikimora is three meters tall and she has eight legs."Furdik then constructed massive Kikimora legs from long plastic pips and made a homemade adversary. "I brought in six people," he said, "and put them on the table." Giving the legs to the guys on the table, Furdik "just stayed under the legs and and started to build the fight."After running through the fight over and over at a slowed down pace, all the moves were taught to Cavill, who never used a stunt double, or a body double of any kind, on The Witcher.Hissrich has revealed that The Witcher: Season 2 will land in 2021 and be much more linear in its storytelling.
