MTV Movies Blog � EXCLUSIVE: Emma Thompson Chooses ‘Nanny McPhee’ Sequel Over Harry Potter: "“The working title is ‘Nanny McPhee and The Big Bang’,” she revealed to us. “It’s not a sequel, actually, it’s a new story.”
The original film had Thompson’s wart-heavy governess employing magic to help a father tame his wild kids. “[The second film] is set one hundred years later; the only thing that is the same is Nanny McPhee,” she explained. “It’s about two families: A family of country children, and a family of town children, [both] during the war. So it’s about evacuees, and the father is away at war. So this time, the lone parent is the mother. That’s what it’s about: The big war, and a war between these two sets of extremely different children.”"
