Family / Fantasy, Released in 2006, Starring Emma Thompson, Colin Firth, Angela Lansbury 

A governess who uses magic and mind tricks to achieve proper behavior of the continually misbehaving children in her charge. She tells the children in her charge “When you need me, but do not want me, then I shall come, when you want me but no longer need me, then I must leave.”

I enjoyed this, it has a strong reminder of Mary Poppins, though with a twist, Nanny McPhee isn’t someone whom everyone always loves. My children watched it more than once and are still talking about it, they loved it.
