On Vacation Location has posted that John Wick will be filming at W 43rd Street and 8th Avenue in Manhattan on Wednesday, November 13.
Schedule is posted here.
Note: Folks in NYC, Long Island, Brooklyn, etc keep their eyes open for yellow signs attached to telephone poles, posts, doors, buildings, etc. That have parking or other restrictions on them for a particular day(s) associated with a specific film, TV show or event. When they find signs, they take a photograph and send it to OVL or tweet them the info on the sign. It looks like the location given on the sign equates to an area around said location. When they give multiple days on the sign it looks like the shoot can be there during the whole time frame or on only some of the day(s) depending on how things go.
It’s not clear if Wick shot near Time Square any time yesterday but the location for shooting today is definitely in the Time Square area. Also, I am not in NYC so the best I can ever do is post info from OVL or folks tweets. It is appreciated when folks in the NYC area provide feed back on location info.
