Brooklyn Castle, a new documentary, is the story of a public school chess team at Williamsburg’s IS 318. With rankings higher than Albert Einstein’s and students from mostly low-income and immigrant homes, this dedicated chess team has captured over 26 national chess titles, more than any other  middle school in the United States.

Facing budget cuts and the threat of losing the chess after-school program, the instructors students and parents band together to help save the program.

This uplifting, must-see film will be presented by Rooftop Films on their very own rooftop in Park Slope/Gowanus on Saturday, July 21. Location: The Old American Can Factory (232 Third St. @ 3rd Ave). Doors open at 7:30PM. At 8PM, there will be a mini-chess tournament. The film begins at 9PM.
