EXCLUSIVE: Directed by Amy Redford [pictured], the modern romance stars Justin Bartha, Olivia Thirlby and Constance Zimmer.

Justin Bartha, Olivia Thirlby and Constance Zimmer have joined the cast of Amy Redford’s next project Phoenix, which she will begin shooting for Micro Films Group in September.

Manifest Film Sales, a division of Intandem Media Group, commences talks with buyers this week on the Croisette.

Playwright Scott Organ wrote the screenplay about a one-night stand between love-averse strangers that sends them on a 4,000-mile trip from Brooklyn to the Grand Canyon and back.

Producers are Buzz Koenig and Paul Urcioli, while Micro Films Group CEO Henri M Kessler serves as executive producer alongside Dawn Krantz and Federico Bauder.

Phoenix is a modern romance that reflects all of the complexities of actually falling in love – navigating hard choices, the absurdity and exhilaration of life,” said Redford, the daughter of Robert Redford who made her directorial debut on Sundance 2008 premiere The Guitar.

“I am inspired by Scott’s authentic, well-crafted script and thrilled to see it realised with Justin and Olivia. They are both first-rate actors and human beings. I can’t wait to get started with them.”

The shoot will take place in New York and the South-west.
