A new documentary that investigates the impact of U.S. drone strikespremiered Wednesday (Oct. 30) in New York City.

The film, called "Unmanned: America's Drone Wars," made its debut Wednesday evening at the Sunshine Landmark Theater in Manhattan. The documentary features Rafiq ur Rehman, a primary school teacher from a mountainous region in northeast Pakistan, whose 67-year-old mother was killed by a drone strike in October 2012. Two of Rehman's children were also injured in the attack.

Earlier this week, Rehman and his children, Nabila and Zubair, traveled to Washington, D.C., to testify before Congress, in what was the first time U.S. lawmakers heard directly from victims of an alleged American drone strike. Rehman and his family were invited to speak on Capitol Hill by Rep. Alan Grayson (D-Fla.).

The full-length feature documentary is directed by Robert Greenwald, who previously produced and directed "Wal-Mart: The High Cost of Low Price" and "Koch Brothers Exposed." The film includes more than 70 separate interviews, including conversations with a former American drone operator; former Secretary of State Colin Powell; former director of the CIA David Petraeus; and Pakistani families mourning loved ones.

More information about the documentary, and screening locations, can be found on the film's official website.
