The play, which had begun previews Oct. 30, will open Dec. 4. The original opening night, Nov. 20, had been postponed due to the stagehands strike. It was previously announced that the the limited engagement of the Tracy Letts opus had been extended by three weeks through March 9, 2008.

The three-act, three-and-a-half-hour drama is billed this way: "When their patriarch vanishes, the Weston clan must return to their three-story home in rural Oklahoma to get to the heart of the matter. With rich insight and brilliant humor, Letts paints a vivid portrait of a Midwestern family at a turning point."
