McKinnon and Kunis will play best friends who unwittingly become entangled in an international conspiracy when one of the women discovers the boyfriend who dumped her actually was a spy.
The comedy will be directed by Susanna Fogel from the script she has written with David Iserson.
The fill will release in the US on July 6 next year and is being overseen by Lionsgate's Peter Kang and Geoff Shaevitz and Imagine's Erica Huggins and Julie Oh.
