The spring’s biggest hit, “The Nanny Diaries,” starring Scarlett Johansson and Laura Linney, is a hit with spring cleaners, too. They’ve noticed the maid in the movie, Maria, is a big fan of Swiffer® Dusters®; she uses it in almost every room of Mrs. X’s chic Manhattan home! That’s why Swiffer is giving away two round-trip tickets to New York City, tickets to “The Nanny Diaries” premiere, two tickets to the after-party, two nights lodging, $500 cash and a prize line-up of Swiffer products.
