The ecstatic moans echoed across the outdoor terrace at 66 Rockwell Place, audible even over the rush of traffic below on Flatbush Avenue.

It was quite the opening for a Friday night movie screening as the actress Natalia Tena straddled the actor David Verdaguer for the first five minutes of “10,000 KM” — a scene made all the more awkward since those in the audience were not sitting among strangers in the dark, but among neighbors familiar from the lobby or the gym.
