The mother-daughter pair penned The Great American Mousical, which contains illustrations by Andrews' ex-husband and Emma's father Tony Walton, back in 2006 and now she's set to stage the theatrical adaptation of the book at the Norma Terris Theater in Chester, Connecticut later this year (12).
Zina Goldrich and Marcy Heisler will compose the music and lyrics and the choreography will be completed by Tony Award nominee Christopher Gattelli.
The Sound of Music veteran tells BroadwayWorld.com, "Emma, Tony and I had so much fun working on this book and are now overjoyed that it will come alive on the stage. I'm so blessed to be working with this creative team in adapting our book for the theatre."
The show is set to open on 8 November (12) and run through 2 December (12).
The play marks the star's second turn at directing - Andrews previously oversaw a revival of The Boy Friend at the Goodspeed Opera House in Connecticut in 2005.
