EXCLUSIVE: Jennifer Ehle (Zero Dark Thirty), Kelvin Harrison Jr. (Mudbound), Emory Cohen (War Machine) Brennan Brown (Focus), and Jeremy Bobb (Going in Style) round out the cast of the Alistair Banks Griffin-directed psychological thriller, The Wolf Hour, starring Naomi Watts as June Leigh (Watts), a cultural icon and activist during the 1960s, now fallen from grace and a shell of her former self.

It’s the notorious “Summer of Sam” and June only has to look out of her window to see the violence escalating with the brutal summer heat. The city is on a knife’s edge, a pressure-cooker about to explode into the incendiary 1977 New York blackout riots. As June retreats further into isolation, an unseen tormentor begins exploiting her weaknesses and her carefully guarded universe begins to unravel.

Griffin penned the screenplay for the film, which recently commenced production in New York. HanWay Films is handling international sales and distribution rights, with CAA aboard to oversee domestic.

Producers are Brian Kavanaugh-Jones and Bailey Conway Anglewicz of Automatik Entertainment along with Bradley Pilz, who will fully finance and produce under his newly minted Bradley Pilz productions. Watts will serve as exec producer alongside Big Picture’s Felipe Dieppa and Taryn Nagle, Belladonna Productions’ Linda Moran, Automatik’s Fred Berger, and Kate Driver. Gabrielle Nadig is co-executive producing.
