The Emmy Award-winning actress is set to play the mother of a teenage girl whose life begins to unravel when she discovers that Sarah's on-screen character is hiding an uncomfortable secret, Collider reports.

Aneesh Chaganty will direct the project from a script he co-wrote with Sev Ohanian, while Natalie Qasabian will co-produce the film alongside Aneesh.

Production on the thriller is set to begin in the next few weeks and will then run through until the end of the year.

Sarah, 43, appeared alongside a star-studded cast in the much-hyped 'Ocean's 8' movie earlier in 2018.

And the acclaimed actress - who worked with the likes of Rihanna, Sandra Bullock, Cate Blanchett and Anne Hathaway - previously admitted to relishing the experience.

She said: "It was so much fun. I got to wear these fabulous coats and be cool and work with these incredible actresses."

Sarah revealed she struck up a particularly close friendship with Sandra, especially as they take similar approaches to work.

She said: "We're incredibly sympatico in how we work, we both love to improvise. And, boy, is she fun."

But in spire of being one of Hollywood's most in-demand stars, Sarah revealed she doesn't watch herself on screen because she's always "disappointed" in her own work.

Sarah explained: "I don't want to be disappointed. I'd be, like, 'Hello, Emmy? Sorry, I got to give this back.'"
