Based on the 1980 film of the same name about a trio of office workers who turn their tables on their sexist and egotistical boss, the show will feature a book by Patricia Resnick, co-author of the film's screenplay, and a score by Grammy Award winner Dolly Parton, who penned the film's hit title song.

The show will star Stephanie J. Block, Megan Hilty, Marc Kudisch, Allison Janney, along with Andy Karl, Kathy Fitzgerald, Ioana Alfonso, Timothy George Anderson, Jennifer Balagna, Justin Bohon, Paul Castree, Daniel Cooney, Jeremy Davis, Gaelen Gilliland, Autumn Guzzardi, Ann Harada, Neil Haskell, Lisa Howard, Van Hughes, Michael X. Martin, Michael Mindlin, Karen Murphy, Mark Myars, Justin Patterson, Jessica Lea Patty, Charlie Pollock, Tory Ross, Wayne Schroder, Maia Nkenge Wilson, and Brandi Wooten.

The creative team will also include Scott Pask (sets), William Ivey Long (costumes), Jules Fisher and Peggy Eisenhauer (lighting), John Shivers (sound), and Stephen Oremus (musical supervision).

Mantello is a two-time Tony Award winner for Assassins and Take Me Out, and is currently represented on Broadway by Wicked and directed the Roundabout Theatre's revival of Pal Joey earlier this season. Blankenbuehler won the Tony, Drama Desk, Outer Critics, and Lucille Lortel Awards for his choreography of In The Heights.
