I do love that witches haven't really been explored that much. Usually, witches are the little side character... a bad female character that comes in and leaves.
I really like supernatural stories, but, to me, 'Witches of East End' is really grounded. It's not just going for the magic tricks and keeping it superficial and action-y.
My first introduction to television, and really just the business in general, was working with David Lynch, with his incredibly open, creative mind that was not following any rules.
I know 'Vikings' isn't really based in magic, but it goes back to Old World spirituality and different religions, and a lot of voodoo.
I really loved 'Witches of Eastwick', the movie with Michelle Pfeiffer and Jack Nicholson and Cher.
