Henry Cavill will hunt monsters as Geralt of Rivia in Netflix‘s “The Witcher,” based on the best-selling fantasy series and debuting on the streaming service on December 20.

But how much will the series lean into the horror elements of the story? Chatting with Games Radar, visual effects supervisor Julian Parry promises a horror-heavy approach!

“I definitely think it leans more towards horror,” Parry told the site.

He continued, “We’re definitely taking the fantasy out. I can honestly say we’re not fantastical. I mean, it’s fantastical but in a grounded horror sense. For example, with Striga [a woman cursed to live as a monster], that’s one gnarly-looking thing. That’s very unpleasant!”

“The Witcher” is an epic tale of fate and family. Geralt of Rivia, a solitary monster hunter, struggles to find his place in a world where people often prove more wicked than beasts.

But when destiny hurtles him toward a powerful sorceress, and a young princess with a dangerous secret, the three must learn to navigate the increasingly volatile Continent together.
