As odd as it may seem, film crews do a lot of shooting around the Gowanus Canal. This set took up quite a bit of space, with catering and support vehicles and all. There is still a graphic book available, called It Came from the Gowanus Canal, for $5. which makes sense, but a film setting seems a bit weird. Usually there is always filming done in Brooklyn Heights, a much more scenic place in Brooklyn. The series Point of Interest was always shooting in Brooklyn Heights, it seemed.
Anyway, I included the image of the church steeple across the canal, closer to Carroll Gardens and this corner shot, as well.
