Look! Up in the sky! FilmRise has acquired North American rights to National Bird, a documentary on drone warfare that screens at Tribeca this week and will get a theatrical rollout in the fall.

FilmRise touts National Bird as “the first film — or any other media story — that has revealed so much firsthand information about the U.S. drone program through on-FilmRise logothe-record sources.” Produced by Errol Morris and Wim Wenders, the film homes in on three whistleblowers who shed light on the U.S.’ secret drone program. The Air Force veterans are tortured by guilt over their participation in the killing of faceless people in foreign countries. Also featuring defense attorney Jesselyn Radack, who represented Edward Snowden, director Sonia Kennebeck’s National Bird looks at the drone-warfare issue through the eyes of veterans and survivors.

“The use of drones in the military is being discussed and debated now more than ever, and we are confident that audiences will respond to this incredibly important film,” Kennebeck said.

The deal for National Bird was negotiated by FilmRise CEO Danny Fisher and VP Acquisitions Max Einhorn with Ben Braun and Josh Braun of Submarine. The film premiered at Berlin and screens Saturday at the Manhattan fest.
