“The Other Woman” grossed more than $196 million worldwide on a budget of $40 million, and now the screenwriter behind the 2014 Cameron Diaz infidelity comedy seems to have another hit on her hands. Deadline reports that Melissa Stack has closed a mid-six-figure deal with Fox for an untitled spec script, and she’ll helm the project. The vacation comedy will mark her directorial debut.

Based loosely on Stack’s own experiences, the R-rated film will center on an older woman who goes on vacation with “her much-younger boyfriend’s family.” The source writes that “Stack got a lot of notice around town a few years ago for her script ‘I Want to _____ Your Sister,’ which Paramount bought, and she is currently rewriting ‘Who Invited Her’ for Universal.” The former is a Black List script about a man whose sister does an internship at his company. As the title suggests, she receives a lot of attention at the business. Amy Schumer is set to topline the latter project, a comedy about a woman who attends her male best friend’s bachelor party.

Stack is a former lawyer. “[I was] going off to court and writing at night and on weekends and trying to make something happen,” she has recalled. “There were nights I would drive home from the law firm and think, ‘Is anything ever going to come together?’ I went to USC to get an MFA in screenwriting and promptly realized that I needed to make money, so I was practicing law part-time and writing, and then I ended up with the script on the Black List and was able to write full-time.”
