Box-Office Milestone: 'Bad Moms' Crosses $100M in U.S.

The female-fueled movie is the first R-rated comedy of the year so far to top $100 million domestically.

Here's to naughty mamas.

Bad Moms, from co-directors Jon Lucas and Scott Moore, will cross the $100 million mark in North America on Saturday, becoming the first R-rated comedy of the year to achieve the milestone. It's a needed win for the genre, and an even bigger win for STX Entertainment (it's the young studio's top-grossing film to date, by far).

Bad Moms' ensemble cast includes Mila Kunis, Kristen Bell and Kathryn Hahn, who play a trio of suburban mothers who decide to rebel against a group of uptight moms, played by Christina Applegate, Jada Pinkett Smith and Annie Mumolo.

The raunchy comedy took in $1.3 million from 2,306 locations on Friday, putting its total at $99.1 million. On Saturday, it will gross another $1.8 million-$1.9 million, according to projections.

The film, largely fueled by females, will turn a handy profit for STX and the other producers of Bad Moms, including Suzanne Todd and Bill Block, considering its modest $20 million production budget. There's almost sure to be a sequel, although a follow-up hasn't been officially announced.

Lucas and Moore, the writing team behind The Hangover, directed from their script.

Most R-rated comedies have struggled of late. Besides Bad Moms, the other exception is Sony and Annapurna's animated adult film Sausage Party, which will finish the Labor Day weekend with north of $90 million domestically on its way to also crossing the $100 million threshold.

Overseas, Bad Moms has earned more than $29 million so far.
