The first fan question has been answered by Gianna Sobol over at Inside True Blood Blog.
The question is: Will the witches wear pointy hats, have crooked noses and have warts or will they look just like me and you… the average but beautiful Jo?
Giana’s response is below:
I talked to Ben Hayes, the writers’ assistant, about this one, because he was in the room when the writers were deciding how to characterize the witches. He said that it was inspired by the characters in the fourth book by Charlaine Harris, but that in bringing Marnie to life, they were trying to create a character that seems real, but slightly “off.” The witches in Season 4 all follow that approach and are a range of personalities and looks.
Ben also shared that “as far as the magic goes, there was a good deal of discussion in how to depict it in a visual medium. The writers wanted the magic to suit the stories and nature of the show, but also to meet the needs and opportunities of production. Several different traditions were researched and discussed in order to come up with a unique take on witches, witchcraft and magic in the world of ‘True Blood.’”
