Scarlett Johansson and her THE NANNY DIARIES co-star Donna Murphy are campaigning to take the movie to the stage - as a new musical. The actresses bonded during the making of the Mary Poppins-esque film, about a struggling New York babysitter, and now they want to turn the project into a sing-along stage spectacular. Murphy explains, "There are references to Mary Poppins in the film and I'd really like to see The Nanny Diaries: The Musical. I hope they cast me in that. "Scarlett and I love to sing and (producer) Harvey (Weinstein) wanted us to have a little duet. He would come on the set every once in a while and say, `Can't they do a little something? You know they both sing?' So Nanny Diaries, The Musical why not? Mary Poppins is one of my favourite movies and my daughter loves it."
