In a rare on-site US deal in this year’s Toronto, A24 has acquired US rights to Noah Baumbach’s ensemble drama, which premieres on September 11 and has already screened for press and industry.

Ben Stiller, Naomi Watts, Adam Driver and Amanda Seyfried star in the story of a middle-aged couple whose lives are disrupted when a young couple enters the fray.

The film also stars Charles Grodin, Adam Horovitz, Maria Dizzia and Ryan Serhant.

While We’re Young is an IACF presentation produced by Scott Rudin, Noah Baumbach, Lila Yacoub and Eli Bush.  

A24 negotiated the deal with UTA on behalf of IACF and the filmmakers. FilmNation handles international sales.
