September is National Preparedness Month, an opportunity for New Yorkers to fortify their apartments, get into the fetal position, and shake uncontrollably get ready for various types of emergencies. And because the city doesn't want you to panic, they're going to kick things off with a pleasant, free movie in the park that may only keep you up for part of the night in terror: Contagion.

Steven Soderbergh's 2011 film—starring Matt Damon, Marion Cotillard, Laurence Fishburne, Jude Law, Gwyneth Paltrow, and Kate Winslet among others—concerns [SPOILER ALERT IF YOU DON'T KNOW WHAT THE WORD CONTAGION MEANS] the global spread of a virus and the breakdown of society in its wake. The film will be shown for free tonight at sunset at Cadman Plaza Park in Brooklyn. BYO surgical mask and hand sanitizer!
