As Mary Poppins celebrates its fifth anniversary on Broadway, a beloved New York City landmark ensured the event would be "practically perfect." On November 15, the Empire State Building invited Mary Poppins star Steffanie Leigh and members of the cast to help light the iconic building in honor of the Disney musical's milestone. After the building's lights were turned blue to match Mary's wardrobe, Leigh headed to the top of the skyscraper (without the help of her magical umbrella!) to take in the sights of Manhattan. Take a look at Leigh's adventure below. Congratulations to the cast and crew of Mary Poppins!
