With construction of the new Barclays Center underway, and the upcoming traffic diversion along Flatbush and Fourth Ave. set to happen July 15, many of us are now seeing the ramifications of the Atlantic Yards project. But for an excellent primer on how we got here, and who tried to prevent this eminent domain abuse, see Battle for Brooklyn tonight at Fort Greene Park. The documentary by local couple Michael Galinksy and Suki Hawley traces Develop Don’t Destroy’s seven-year fight against AY on the streets and in hearings, and provides an intimate character study of Daniel Goldstein, the apartment owner-turned-activist who wages a heroic fight against Forest City Ratner. Rev. Billy will deliver a sermon at 8:30 before the free, 9pm Rooftop Films screening, followed by a Q&A with the directors and Goldstein. It then opens at Cinema Village and indieScreen on June 17.
