A new trailer for Nanny McPhee and the Big Bang has been released. The sequel to Nanny McPhee stars Emma Thompson (Trelawney), Ralph Fiennes (Voldemort), Maggie Smith (McGonagall), and Rhys Ifans (Xenophilius Lovegood).  This film is one of the reasons that Emma decided not to return to play Trelawney in Deathly Hallows, among other things.

Thanks SS!
