Kate McKinnon has officially joined the ranks of all the SNL stars before her who went from TV to movies at lightning speed. After this summer’s Ghostbusters, McKinnon has Office Christmas Party coming up this weekend, and today it was announced that she will be playing the titular spellcaster in Amblin’s adaptation of The Lunch Witch.

Deadline reports that McKinnon has signed on to play Grunhilda, the title character in Deb Lucke’s YA book who becomes a school lunch lady due to her ability to brew up truly gross concoctions. The movie adaptation will be directed by Angry Birds co-director Clay Kaytis, in his live-action directing debut. Angry Birds wasn’t exactly an Oscar contender, but hopefully a medium other than CGI and a star as ridiculously talented as McKinnon will quell any worries on that account. And McKinnon’s best roles are her truly weird SNL characters, like Russian peasant Olya Povlatsky and the alien abductee who almost made Ryan Gosling giggle himself to death, so it seems almost comical that she hasn’t been offered a witchy role until now.

Here’s the plot synopsis of the book:

For generations and generations, the women of Grunhilda’s family have stirred up trouble in a big, black pot. Grunhilda inherits her famous ancestors’ recipes and cauldron, but no one believes in magic anymore. Since her only useful skill is cooking up potfuls of foul brew, she finds herself uniquely qualified to hire on as school lunch lady. Grunhilda delights in scaring the kids until she meets a timid little girl named Madison with a big set of glasses who becomes an unlikely friend. Madison needs help at school and at home, but helping people goes against everything Grunhilda’s believes in as a witch. Will she stir up trouble with her brood?

The Lunch Witch does not yet have a release date.
