Bright Star,” the bluegrass musical by Steve Martin and Edie Brickell, has locked in its Broadway details, setting a March opening with a cast headed by Carmen Cusack, who originated the lead role in the show’s world premiere production in 2014.

Cusack will appear with a cast that includes Paul Alexander Nolan, Michael Mulheren, A.J. Shively, Hannah Elless, Stephen Bogardus and Dee Hoty, among others, all of whom will also play in the show’s pre-Broadway engagement at Washington, D.C.’s Kennedy Center, where the musical will open Dec. 17. The musical initially bowed at San Diego’s Old Globe Theater in 2014.

“Bright Star” centers on a literary editor (Cusack) whose meeting with a young soldier fresh home from World War II (Shively) prompts her to come face to face with her past. Martin pens the book and co-writes the music with composer-lyricist Brickell, basing the musical on their Grammy-winning country-bluegrass album “Love Has Come For You.”

Produced by Joey Parnes, who also led the producing team of  Tony winner “A Gentleman’s Guide to Love and Murder,” “Bright Star” is directed by Walter Bobbie (“Chicago”) with choreography by Josh Rhodes. The Broadway transfer will begin previews March 7 ahead of a March 31 opening at one of the theaters owned by the Shubert Organization, with the exact house to be determined based on availability in the coming weeks.
