I am inspired by both Japanese Samurai films, in particular the films of Kurosawa, and how they share the spirit of American Westerns, with the influences running in both directions, and including the 'Spaghetti Westerns' and films of Sam Peckinpah.
The thing that influenced me most in relation to 'Nanny McPhee' were the Westerns I watched with my father. All the Spaghetti Westerns; all the Virginians; all the High Chaparrals. Because if you think about the form, it's a stranger from out of town.
