STX Entertainment has set Aug. 19 as the opening date for its untitled moms comedy starring Mila Kunis, Christina Applegate and Kristen Bell.

Jon Lucas and Scott Moore are directing the movie, previously titled “Bad Moms,” from their own script. Suzanne Todd (“Alice in Wonderland”) and Bill Block are producing.

The film follows three moms who embark on a quest to liberate themselves from their mundane, everyday chores, accidentally landing themselves on a collision course with their children’s school’s PTA president and her blindly devoted clique of “perfect” moms.

STX also set its untitled coming of age comedy, starring Hailee Steinfeld, for a Sept. 30 opening. The project, known as “Besties,” also stars Woody Harrelson, Kyra Sedgwick, Haley Lu Richardson, Blake Jenner and Hayden Szeto.

Kelly Fremon Craig is directing from her own script. Producers are James L. Brooks, Richard Sakai and Julie Ansell.

STX also gave a pre-Halloween date of Oct. 14 to its horror-thriller “The Bye Bye Man,” starring Carrie-Anne Moss, Faye Dunaway, Douglas Smith, Cressida Bonas, Lucien Laviscount and Douglas Jones. Stacy Title is directing from a script by Jonathan Penner from the short story “The Bridge to Body Island” by Robert Damon Schneck.

Producers are Trevor Macy, Jeffrey Soros and Simon Horsman.
