Roundabout Theater Company (Cabaret, Major Barbara) has lined up an all-star cast for Clare Boothe Luce’s classic tale set around the gossipy lives of a group of well-to-do Manhattan women. Cynthia Nixon (Sex and the City) plays Mary Haines, a wealthy woman who learns that her husband is cheating on her with a common shopgirl (played by Bullets Over Broadway star Jennifer Tilly) from a gossipy manicurist. This catty, classic comedy also stars Kristen Johnston (3rd Rock From the Sun), Rue McClanahan (The Golden Girls) and Mary Louise Wilson (Full Gallop).
