Moviefone recently premiered the trailer for the Scarlett Johansson-starring comedy THE NANNY DIARIES. Based on the Emma McLaughlin and Nicola Kraus novel of the same name, Johansson stars as the titular nanny for an upper class Manhattan family of which Laura Linney is the mother and Paul Giamatti the father. As if caring for their bratty, spoiled child isn’t enough, Linney, being an accomplished she-devil, tortures Johansson with an endless number of tasks and demands. And, of course, there’s a boy. Chris Evans, to be exact. Whom she meets with quite literally her pants down. Despite the awkward encounter, however, he helps her in many ways, not the least of which is in the “getting laid” department. Check out the trailer and all its accompanying hijinks over HERE. The film opens April 20th.
