The film will world premiere at Sundance before its release later this year.
Baumbach directed from a script he co-wrote with Gerwig. The film is produced by Baumbach, Scott Rudin, Lila Yacoub, Rodrigo Teixera and Gerwig.
Teixera’s RT Features financed “Mistress America.”
Kirke portrays a lonely college freshman in New York who’s not having an exciting university experience or the glamorous metropolitan lifestyle she envisioned. She’s rescued from her disappointment by her soon-to-be stepsister, an adventurous resident of Times Square portrayed by Gerwig.
The deal was brokered by Fox Searchlight’s Tony Safford, Megan O’Brien and Ray Strache with the UTA Independent Film Group, which represented the filmmakers and arranged the film’s financing.
RT Features helped develop, produce and finance “Frances Ha,” which starred Gerwig and was directed by Baumbach. It also produced Ira Sachs’ “Love Is Strange,” is developing a James Gray project and announced a venture last year with Martin Scorsese’s Sikelia Prods., launching a fund to finance and produce projects by emerging filmmakers.
