What fine rump Henry Cavill has - a super bottom, you could say - so why not slap it on the poster for Netflix's new Witcher TV show?
Exactly. Which is why Cavill, turned away from camera, decked out in full Witcher garb, is the lead image for the show. And it's a clever shot, because bum aside, it's how you see Geralt (the character Cavill is playing) for hours and hours when you play The Witcher 3: Wild Hunt video game. It's familiar. It's saying, "This is the character you know."
Oh, and his carrying only one sword in place of the two you're used to seeing him with in the games? As people have pointed out in the comments below: Geralt carries one sword in the books, leaving the other with his horse Roach for when he needs it. And the show, remember, is based on the books, not the games.
