Westport Country Playhouse will stage Terrence McNally's "Lips Together, Teeth Apart," directed by playhouse artistic director Mark Lamos, from July 12 to 30.

The third production in the playhouse's 80th year, the play is a comedy with conflicts about two straight couples spending a July weekend on Fire Island.

In a beach house, a brother and sister and their respective spouses gather to celebrate the Fourth of July. With food, cocktails, fireworks and barbs, they fortify themselves against their anxieties -- and gay neighbors partying in the houses on either side. The play contains adult content and language.

The cast includes Chris Henry Coffey as John Haddock, John Ellison Conlee as Sam Truman, Jenn Gambatese as Chloe Haddock and Maggie Lacey as Sally Truman.

The design and production team includes Andrew Jackness, costume design; Robert Wierzel, sound design; Mark Silence, fight director; Matthew Melchiorre, production stage manager; Amanda Spooner, assistant stage manager; and Janet Foster, casting.

After "Lips Together, Teeth Apart," the playhouse's five-play 2011 season will continue with "Suddenly Last Summer," a drama by Tennessee Williams and directed by David Kennedy, the playhouse's associate artistic director, Aug. 23 to Sept. 10; and "Twelfth Night, or What You Will," the comedy/romance by William Shakespeare and directed by Lamos, Oct. 11 to Nov. 5.
