Emma Watson, in town filming Darren Aronofsky’s “Noah” with Russell Crowe, has been helping New Yorkers after Hurricane Sandy. We’re told Watson, whose biblical epic shut down production ahead of the storm, has been delivering meals to the city’s homebound elderly with Citymeals-on-Wheels. Sandra Lee, Paula Zahn, Samantha Boardman, Lizzie Tisch and Victoria Vargas D’Agostino are just a few of the who have volunteered with the charity.
