After the protagonist Geralt, who will be played by Henry Cavill, the other two leading characters for the series the Witcher have found their faces in the flesh.
These are two of the major comprimarie of the protagonist: Ciri will be played by Freya Allan (The War of The Worlds, Bluebird), while Yennefer is entrusted to Anya Chalotra (Wanderlust, The ABC Murders). Taking into consideration the depiction of the two women in the video game version of The Witcher, you will notice the similarities of the somatic in the two actresses, perhaps more for the Allan, with regard to Chalotra, but you have to remember that, in the ideas of the showrunner Lauren Schmidt Hissrich, the series on Netflix about The Witcher is inspired by the universe the series created by Andrzej Sapkowski and not video games in particular (although the same Hissrich it is defined as a fan of the series from CD Projekt RED).
In both cases, these are names less known than Cavill, however, the cast that the production is putting together for this new series, Netflix is proving to be interesting. There is still a period for the publication of The Witcher, with filming due to start soon.
