A teaser trailer for the second Nanny McPhee film is now online!  Emma Thompson plays Nanny McPhee and is also the one of the producers and writer of the movie.  For that reason she was not able to return to film Deathly Hallows, which is a disappointment to all Potter fans as she was the PERFECT Trelawney.  Other Potter stars are also in the film:  Ralph Fiennes will be playing Lord Gray and Maggie Smith will play Mrs. Docherty, finally, Rhys Ifans is playing Uncle Phil.
