O'Hara previously arranged a 15-day summer break (July 15-29) from the fizzy Gershwin musical in order to rehearse and perform the developing musical Far From Heaven, at Williamstown Theatre Festival in Massachusetts. O'Hara will also star in the Off-Broadway premiere of that show in spring 2013 at Playwrights Horizons.

Dilly is remembered by fans of classic musicals for her bright starring performance as Billie in the Encores! concert of Rodgers and Hart's Babes in Arms (later captured on a concert cast album). She joins the Nice Work troupe — also playing a character named Billie, this time a lovesick bootlegger, Billie Bendix — at the Imperial Theatre on July 15. Four-time Tony nominee O'Hara returns on July 31.

Dilly was last seen on Broadway as Truly Scrumptious in Chitty Chitty Bang Bang, for which she was nominated for Tony & Outer Critics Circle Best Actress awards. She also appeared on Broadway in Follies (Young Phyllis), The Boys From Syracuse (Lucianna) and Into the Woods (Cinderella). She starred in the national tours of South Pacific (Nellie), Martin Guerre (Bertrande) and Beauty and the Beast (Belle). Her films include "Julie and Julia," "Too Big to Fail," "Everyday People," "12 Men of Christmas" and the upcoming "My Friend Vijay" and "The Diary of Preston Plummer."

Regional audiences have seen her at Guthrie Theatre, The Alley Theatre, Goodspeed Opera House, Berkshire Theatre Festival and elsewhere.

Nice Work If You Can Get It won two 2012 Tony Awards (for featured actors Judy Kaye and Michael McGrath). It has music and lyrics by George Gershwin and Ira Gershwin and a book by two-time Tony Award-winner Joe DiPietro. Two-time Tony Award winner Matthew Broderick plays playboy Jimmy. The production is directed and choreographed by three-time Tony Award-winner Kathleen Marshall. Visit NiceWorkOnBroadway.com.
