Henry Cavill starred in the Netflix series The Witcher for three seasons. Then he announced he would be leaving the series, with Liam Hemsworth taking over the role.

"My journey as Geralt of Rivia has been filled with both monsters and adventures," Henry said. "In my stead, the fantastic Mr. Liam Hemsworth will be taking up the mantle of the White Wolf.

Then, Liam released his own statement saying, "Henry Cavill has been an incredible Geralt, and I'm honoured that he's handing me the reins and allowing me to take up the White Wolf's blades for the next chapter of his adventure.... I may have some big boots to fill, but I'm truly excited to be stepping into the Witcher world."

Kristen Stewart reminisced with Nicole about their brief time on set together, "We spent a couple of weeks rehearsing and like — I know you. I was a little guy but — it's an interesting time to meet somebody and have a vivid memory of it because the way that you treat kids, is so telling of you — of anyone.
