Wise talks about the difficulty choreographer Jerome Robbins faced in creating a vocabulary of dance moves for the (relatively for that time) realistic New York streets. Wise was immensely concerned with the setting. He also talks about the idea of opening the film with epic helicopter shots of the city.

They shot on a street that had been condemned and abandoned (to build the present-day Lincoln center). They were able to make a deal with contractor to hold off on tearing it down so they ended up with a very authentic New York street as their own private backlot.
