If you enjoyed Emma Thompson's portrayal of Professor Trelawney, you'll be sure to fall in love with her as Nanny McPhee! Here, Thompson transforms into a magical nanny with physical quirks. After the death of their mother, the Brown children have had a hard time adjusting, driving out every nanny who comes their way. Luckily for their father (Colin Firth), the one person who's able to get them under control is Nanny McPhee, who, as the children suspect, is a witch. Even if they don't immediately warm up to this magical caretaker, the children come across a greater nemesis: Aunt Adelaide (Angela Lansbury). With a more sinister adult in their lives, the only person who can help them is Nanny McPhee.
