Henry Cavill's love of nerd culture is well-known, and he's been vocal about his love of video games, sci-fi and fantasy.
There's been no official explanation for his departure from The Witcher, but it's been suggested creative differences played a part.
He's spoken in interviews about being "loyal to the source material" and the importance of keeping Geralt the same as the character in the books.
Since leaving, he's landed a role as a producer and star of Amazon's upcoming Warhammer 40,000 series - something he's described as a dream role.
Sabrina Barr, TV Editor at Metro, says Henry Cavill was the "epitome of Geralt", and admits seeing Hemsworth in the role was "jarring" at first.
But she tells Newsbeat he he does a "good job" and is "brave" for taking on the character.
