After a widely beloved turn as Jillian Holtzmann in “Ghostbusters” this year, Kate McKinnon will be getting a movie of her very own. As Deadline reported, the “SNL” star will lead in an adaptation of Deb Lucke’s YA comics series The Lunch Witch. In the books, the witchy Grunhilda takes a job as a school lunch lady based on her family’s penchant for stirring up magical brews. (No one believes in magic anymore, so times are tough.) She enjoys scaring her cafeteria charges until she warms up to a young outsider. If McKinnon’s previous roles are any indication, it should be a hoot. The film is to be directed by Clay Kaytis, one half of the directorial team behind “Angry Birds.” Check out Lucke describing the creation of The Lunch Witch below. While we wait for McKinnon to don her hairnet, you can catch her in “Office Christmas Party,” opening Friday.
