When it closes, the production — starring four-time Tony nominee Tovah Feldshuh in the title role — will have played 21 previews and 105 regular performances.

Directed by Michael Parva, Irena's Vow began previews March 10 and opened March 29.

The cast also features Sandi Carroll, Tracee Chimo, Steven Hauck, Scott Klavan, Peter Reznikoff, Thomas Ryan, Gene Silvers, John Stanisci and Maja Wampuszyc.

Irena's Vow, according to the producers, "is the uplifting true story about one of the most courageous and unsung heroines of World War II. During the German occupation of Poland, Irena Gut Opdyke (Feldshuh), a Polish Catholic, was forced to work as head housekeeper for a very prominent Nazi major. Over a two year period of service, Irena would risk her own life in order to save the lives of twelve Jewish refugees whom she secretly took under her care. Irena's Vow is the extraordinary story of one woman's choice and the twelve lives that would ultimately be saved — or lost — by her decision."

The design team comprises Kevin Judge (scenic design), David Castaneda (lighting design), Astrid Brucker (costume design), Quentin Chiappetta (sound design/composer) and Alex Koch (projection design). The play was produced on Broadway by Stan Raiff, Daryl Roth, Debra Black, James L. Nederlander/ Terry Allan Kramer and Peter Fine.

Tovah Feldshuh received Tony Award nominations for her work in Golda's Balcony, Yentl, Sarava and Lend Me a Tenor. Her theatre roles have also garnered the actress four Drama Desk Awards, four Outer Critics Circle Awards, an Obie and a Theatre World Award.
