In five seasons of playing Lucky Luciano on HBO’s “Boardwalk Empire,” Vincent Piazza never had to shoot scenes on a Sunday. “Sunday is a reflective day, a thoughtful day,” he said. Now, with the show heading toward a promised bloody end later this fall, Mr. Piazza has plenty to reflect on, including, as of earlier this year, a new neighborhood to call home. A native of Queens, Mr. Piazza, 38, speaks with a New York brio that makes a 40-block move sound like a journey across temperate zones. His new home, which he shares with his girlfriend of a year and a half and a miniature longhaired dachshund, is near the Ed Koch Queensboro Bridge. But Queens is not too far away. “It’s a pretty incredible thing to know I can walk across the bridge and end up there if I ever need to,” he said.
