When it comes to the idea of "witches" in cinema, we often revert to ancient tropes. Warty chins and pointed hats. Old crones who have been warped and disfigured by a lifetime (or many lives) of dark arts practice. Broomsticks in the air and youngsters in cages, while the oven preheats properly. You know, typical witchery. But depicting witches isn't nearly as straightforward as that. For one thing, in film, they aren't necessarily evil powers.
