what movie is being shot on Prospect Place?

Prospect Place btw Vanderbilt & Underhill there are signs saying no parking because of film shooting on Tuesday the 3rd....

The signs should say what the filming is of -- not sure what it is, though. Gossip Girl was filming car crash scenes in Crown Heights this weekend.

Filming in Brooklyn has nothing listed for the 3rd.

seems a mystery for now
just says "Film Shoot" on all the signs

From what the production assistant said it's called 4.3.2.1:
