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. ↗
I'm not a great science fiction fan myself. I probably feel that way about Westerns. Like I used to play Cowboys and Indians, they can act out Will and the Robot. ↗
