Do you have what it takes to be a “Williamsburg Extra” and take part in a cool Burg party scene in the indie film The Greatest, which will have a “legendary cast”? Well, your moment has arrived. We found these fliers up around N. 6 St. and Berry St. seeking “cool, eclectic people.” The downside is that the workday will start at 7AM, which could have some downsides. The synopsis, per IMDB, is: “A drama that is centered around a troubled teenage girl and a family that is trying to get over the loss of their son.” The stars include Susan Sarandon and Pierce Brosnan. We’re guessing somebody ends up a hipster party in the Burg. Do Greenpoint and Bushwick people qualify to be Williamsburg extras?
