The annual new play event will celebrate its 10th year at the Costa Mesa, CA, stage May 4-6 with seven plays.

Over the course of three days, audiences may take in a workshop production, four staged readings and two fully staged world premieres. Those premieres include Julie Marie Myatt's My Wandering Boy and David Wiener's System Wonderland.

"We are pleased to announce that this year's festival will feature new commissioned works by Richard Greenberg and Donald Margulies, two pre-eminent American playwrights who have long been associated with SCR," said Co-Festival director John Glore (who heads the event with Megan Monaghan). The titles of Greenberg and Margulies' new works have yet to be announced.

Tony Award winner Greenberg (Take Me Out) has previously penned SCR commissions A Naked Girl on the Appian Way, The Violet Hour, Everett Beekin, Hurrah at Last, Night and Her Stars, The Extra Man and Three Days of Rain. SCR has presented those works as well as The Dazzle.

Pulitzer Prize winner Margulies (Dinner with Friends) also enjoyed SCR commissions for Collected Stories, Sight Unseen and Brooklyn Boy — all presented by the company as well. Other plays include The Model Apartment, The Loman Family Picnic and What's Wrong With This Picture? The complete 2007 PPF lineup will be announced at a later date.

South Coast Repertory currently presents Greg Kotis' Pig Farm (through Jan. 28) and will continue its season with Nilo Cruz's adaptation of Pedro Calderón de la Barca's Life is a Dream (Feb. 2-March 11), Julia Cho's new The Piano Teacher (which marks the 100th world premiere production for the company) (March 11-April 1), Marie Myatt's My Wandering Boy (March 30-May 6), David Wiener's System Wonderland (April 22-May 13) and the Daniel Sullivan directed staging of William Shakespeare's Hamlet.
