It’s not summer yet, but the NYC film festival, Rooftop Films, is having a special indoor screening of the new documentary Brooklyn Matters on Monday, March 19th at 7 p.m., at the Old American Can Factory in Gowanus, Brooklyn. And the best part? It’s free.

This is a film protesting the impending mega-development of the Atlantic Yards section of downtown Brooklyn. Developed by Forest City Ratner and designed by Frank Gehry, it would include a sports arena for the Nets pro basketball team that will move from NJ to Brooklyn, lots of new office space, retail shops and middle-income housing. The problem? To build it, they have to kick out a ton of families already living there, the new massive structures will cast perpetual nighttime over the surrounding non-developed areas and it will take at least 10 to 15 years to complete

You can read more about the film at the movie’s official website and watch the trailer (psst, guys, YouTube it). If you want a little more background on the development project, a good place to start is Curbed.com. (I read the L.A. version just about everyday.) Sounds like a pretty contentious, complicated situation and while the film is obviously opposed to the project, the trailer makes it look like they give voice to both sides.

And if you’re interested in the film, but can’t make it to this specific screening, it’s also playing around the city throughout March and into April. Additional screening info is on the film’s homepage.
