Scarlett Johansson and her ‘The Nanny Diaries’ co-star Donna Murphy are at the helm of a campaign to turn the new film, which opened at in a disappointing sixth place over the weekend, into a new musical. The Mary Poppins-esque film chronicles the life of a struggling New York City babysitter.

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?’
