Some of Mila Kunis' most memorable movies, like "Ted" and "Forgetting Sarah Marshall," are raunchy ones.

"There's clearly some part of me that responds to R-rated comedies," Kunis said at the recent CinemaCon in Las Vegas. "I just love fart jokes, I'm sorry."

In "Bad Moms," Kunis, Kathryn Hahn and Kristen Bell play the title characters, overstressed moms who rebel against the having-it-all parenting mentality — and find themselves battling the local PTA queens (played by Christina Applegate, Jada Pinkett Smith and "Bridesmaids" co-writer Annie Mumolo).

All six performers are moms themselves, and they said they could relate to the mental strain being mined for comedy by "Hangover" writers Jon Lucas and Scott Moore (who co-directed).

"Since I became a mom, my life sort of became R-rated," Mumolo said.

"Bad Moms" is expected in theaters July 29. See the full list of movies set for this summer at http://www.sltrib.com/entertainment/3817653-155/summer-movie-preview-blasts-from-the .
