Foster and Henry received Tony Award nominations for their performances as Violet and Flick, respectively, and director Leigh Silverman was nominated for Best Director of a Musical. The production was also nominated for Best Revival of a Musical.
The cast also includes Alexander Gemignani (Les Misérables, Sweeney Todd) as Father, Ben Davis (A Little Night Music, Anna Nicole the Opera) as Preacher, Annie Golden ("Orange Is The New Black," Assassins) as Hotel Singer/Old Lady and Emerson Steele (A Christmas Carol, Annie) as Young Violet.

The Broadway premiere is based on the 2013 New York City Center Encores! Off-Center production, which starred Foster and was directed by Silverman. Violet premiered Off-Broadway at Playwrights Horizons in 1997; it won the Obie Award, Drama Critics’ Circle Award for Best Musical and the Lucille Lortel Award for Outstanding Musical.
"Violet tells the story of a young woman’s quest for beauty amidst the image-obsessed landscape of the 1960s," according to the Roundabout. "Facially disfigured in a childhood accident, Violet (Foster) dreams of a miraculous transformation through the power of faith. Convinced that a televangelist in Oklahoma can heal her, she hops a Greyhound bus and starts the journey of a lifetime. Along the way, Violet forms unlikely friendships with her fellow riders, who teach her about beauty, love, courage and what it means to be an outsider."
The creative team includes David Zinn (sets), Clint Ramos (costumes), Mark Barton (lights) and Leon Rothenberg (sound).
