Emma Watson has been helping New Yorkers affected by Hurricane Sandy, according to reports.

The actress, 22, has been in the Big Apple filming Darren Aronofsky's movie Noah with Russell Crowe.

The New York Post's Page Six reported that the former Harry Potter star has been delivering meals to the city's homebound elderly with Citymeals-on-Wheels.

The report comes after biblical epic Noah shut down production because of the storm.

Filming in Long Island, New York, was halted, reportedly to protect the huge ark which has been built for the movie.
