From what I've read, the film was a surprise hit worldwide; a sequel is currently filming. Having lived most of my life in NYC, I always wonder why the police never appear during these prolonged gun battles! The exteriors for the nightclub were shot on Chambers Street, the northern border of City Hall Park.That buillding houses Manhattan Surrogate's Court. When Wick crosses Chambers, you can see the arched passage of the Municipal Building in the background, and the lights of Police HQ through that archway. Would've been a huge PD response in real life!

P.S. Off topic, but does anyone recognize the building standing in for the hotel? I don't.
