Despite the success of the likes of Bridemaids, The Heat & Spy, Paul Feig took a lot of heat for the relative failure of last year’s Ghostbusters. However, he’s not going sticking with comedy for his next movie, as he’s planning a thriller called A SImple Favor, according to Deadline.

Anna Kendrick and Blake Lively are already in talks to star in the movie, which Feig is writing himself, based on the book of the same name by author Darcey Bell. Here’s the synopsis: ‘It starts with a simple favor—an ordinary kindness mothers do for one another. When her best friend, Emily, asks Stephanie to pick up her son Nicky after school, she happily says yes. Nicky and her son, Miles, are classmates and best friends, and the five-year-olds love being together—just like she and Emily. A widow and stay-at-home mommy blogger living in woodsy suburban Connecticut, Stephanie was lonely until she met Emily, a sophisticated PR executive whose job in Manhattan demands so much of her time.

‘But Emily doesn’t come back. She doesn’t answer calls or return texts. Stephanie knows something is terribly wrong—Emily would never leave Nicky, no matter what the police say. Terrified, she reaches out to her blog readers for help. She also reaches out to Emily’s husband, the handsome, reticent Sean, offering emotional support. It’s the least she can do for her best friend…

‘Soon, Stephanie will begin to see that nothing—not friendship, love, or even an ordinary favor—is as simple as it seems.’

The plan is to start shooting in August, for release next year.
