Ghostbusters sequel, is directing as well as adapting Chainani’s debut bestseller alongside writer David Magee ( Finding Neverland, Let It Snow). Laced with the very Harry Potter-esque idea that magic wielders can sort into training that taps either their good or wicked natures, the story features a pair of schools that do just that — if, that is, they can manage to enroll the right kind of students. Things get jumbled when two best friends — the good-natured Sophie (Sophia Anne Caruso) and the darker-minded Agatha (Sofia Wylie) — each end up at the wrong place, charting unexpected courses for Sophie’s princess-like aspirations and Agatha’s path to villainy.
