Well damn.
Cavill is moving away from The Witcher, and Liam Hemsworth is going to take over for season 4.
Not being a huge fan of the games, and the story still very early in the lore, Cavill was one of the big things about the series keeping me there. I guess I will have to see where season 3 ends to see if I will care at all to continue.
Though Cavill apparently has a bunch of other projects he has lined up, mixed now with commitments to WB... It seems it was either playing Superman or Geralt... And the man of steel won out.
