UPDATED with more information. A week before its official out-of-town opening, Waitress, the new musical based on the 2007 feature film, has announced its move to Broadway. The show will begin previews in March and open in April at the Nederlander Organization-owned Brooks Atkinson Theatre. It’s currently running at the American Repertory Theater in Cambridge, MA, where it opens August 20 and continues through September 27. Jessie Mueller, who won a Tony Award for the title role in Beautiful: The Carole King Musical, stars as Jenna (played in the film by Keri Russell), a young woman pregnant and unhappy in marriage and work in a small-town diner, whose chief source of pleasure is making pies.

Staged by ART artistic director Diane Paulus (whose Broadway credits include Finding Neverland, which also tried out at American Rep), Waitress has a book by Jessie Nelson and songs by singer-songwriter Sara Bareilles, based on the film written and directed by the late Adrienne Shelly. It will be produced on Broadway by veterans Barry and Fran Weissler and Norton and Elayne Herrick. Full casting and other credits will be announced at a later time.

Before Waitress moves in, the Brooks Atkinson will be home to the acclaimed revival of Spring Awakening, which will have a limited run from September 8 to January 9.
