The Witcher showrunner Lauren Hissrich has confirmed that Netflix’s adaptation of the story of Geralt won’t draw from CDProjekt Red’s video games, but has hinted that there will be a scene that pays service to fans.
“There is a bathtub this season,” Hissrich told iO9, in reference to the fan favourite image of Geralt in a wooden tub from The Witcher 3. “I won’t tell you who’s in the bathtub, but there’s a bathtub.”
