This fall, Mary Poppins — er, actress and singer Julie Andrews — is directing a new musical entitled “The Great American Mousical,” based on the children’s book of the same name she co-wrote with her daughter, Emma Walton Hamilton. Goodspeed Musicals will put on the production at the Norma Terris Theater in Chester, Conn., from Nov. 8 to Dec. 2. Though Andrews has directed musicals before, this is the first original show she will have organized — though it shouldn’t be too hard for her, considering she wrote all the original material. In addition, the sets and costumes will be designed by Tony Walton, Emma’s father and the original illustrator for the book. Sounds like a success-in-the-making to us. [via ArtsBeat]
