Director Scott Elliott and Nohilly (who is making his playwriting debut) have been working on the play throughout previews and have delayed the opening by one week, to Jan. 12, 2011, in order to allow the cast to incorporate the modifications. Blood from a Stone was originally scheduled to open Jan. 6, 2011.

"This is a great big play by an exciting new voice, Tommy Nohilly. As we’ve worked through the rehearsal process and had our first previews we’ve made a few significant changes and have delayed opening night to allow several additional preview performances for those changes to knit together," Elliott said in a statement.

In addition to Hawke, Lyonne and Rubin-Vega, the cast includes Gordon Clapp, Ann Dowd and Thomas Guiry.

The New Group describes the play as "an unflinching and darkly comic depiction of life in blue collar Connecticut, [which] zeroes in on a working class family wrestling to keep it together as day-to-day struggles exert their squeeze. When Travis pays a visit to his parents' home, he finds an already volatile household imploding and his close-knit but deeply conflicted family teetering on the brink."

Clapp and Dowd play parents, Bill and Margaret; with Hawke and Guiry as their sons, Travis and Matt; and Lyonne as their daughter, Sarah. Rubin-Vega is cast as their neighbor, Yvette.

Blood From a Stone has set design by Derek McLane, costume design by Theresa Squire, lighting design by Jason Lyons, sound design by Bart Fasbender and special effects by Jeremy Chernick. Doug Paulson is dialect coach.

Performances are scheduled through Feb. 5, 2011. For tickets to The New Group shows at The Acorn @ Theatre Row, 410 West 42nd Street, call (212) 239-6200. For further information visit thenewgroup.org.
