Set to begin previews May 11, the new work directed by Maria Mileaf (Private Jokes, Public Places) will close out the season for the Off-Broadway troupe. The Argument follows the "funny and heartbreaking" tale of "what happens when a couple find themselves at a critical divide in their relationship," according to a release. The three member cast will be announced shortly.

Gersten-Vassilaros co-wrote the play Omnium Gatherum with Theresa Rebeck — which was a Pulitzer Prize finalist last year — and also penned the Broadway play My Thing of Love. As an actress, she appeared last season at the Vineyard in Nicky Silver's Beautiful Child. She has also performed in Alone Together, Lusting After Pipino's Wife, Made in Heaven, Ladies and Loose Ends.

Director Mileaf — who is slated to helm the upcoming Going to St. Ives at Off Broadway's Primary Stages — also staged Oren Safdie's Private Jokes Public Places and the New York premieres of Monsieur Ibrahim and the Flowers of the Koran, Lobster Alice, Those Who Can Do, Hard Feelings. Other credits include Tomorrowland, Maid, 99 Histories and the national tour and Chicago productions of Yasmina Reza's ART.

The Vineyard currently houses the Gina Gionfriddo play After Ashley playing an extended run through April 3 with stars Kieran Culkin and Anna Paquin. The world premiere of Kirsten Childs' Miracle Brothers directed by Tina Landau will be delayed two months to accomodate casting schedules, according to the Vineyard. Previews will begin late August for a Septemeber opening.
