The production is currently booking for performances to May 2, and is directed by Jamie Lloyd.

In the play, Walker Janeway (James McAvoy) and his sister Nan (Marshal) reunite for the reading of their father's will in the Manhattan loft where he lived. A wealthy architect, Ned's legacy is the iconic, internationally renowned 1960s New York house designed with his late business partner Theo. Joined by Theo's son Pip (Nigel Harman), the three childhood friends meet to settle the estate and determine the future of the house. The discovery of a brief entry, "three days of rain," in Ned's diary is the only clue to the true stories of the previous generation. According to press materials, the play "explores how the private worlds of one generation are reinterpreted by the next. A tender and surprising story of love lies at the heart of a creative conflict that could never have been imagined by these children. The actors play both generations in this humorous and touching play about family and the enigma of parenthood."

McAvoy (Walker/Ned) is best known for his film roles in "Atonement" (for which he received both a Golden Globe and BAFTA nomination), "The Last King of Scotland" (for which he was also BAFTA nominated), "The Chronicles of Narnia," "Bright Young Things," "Becoming Jane" and "Wanted" (opposite Morgan Freeman and Angelina Jolie). He is in the upcoming "The Last Station," co-starring Helen Mirren, that is due for release in 2009. TV credits include "White Teeth," "State of Play" and "Shameless." Onstage he has appeared in Breathing Corpses (Royal Court's Theatre Upstairs), Out in the Open (Hampstead Theatre, directed by Kathy Burke) and Privates on Parade (Donmar Warehouse, directed by Michael Grandage).

Harman (Pipo/Theo) is best known for his role in TV's "EastEnders," and he is soon to lead in "Hotel Babylon." Other TV credits include "Lark Rise to Candleford" and "The Friday Night Club." Theatre credits include The Caretaker at Sheffield and the Tricycle directed by Jamie Lloyd, Privates on Parade at the Donmar Warehouse (alongside McAvoy) and Guys and Dolls in the West End, both directed by Michael Grandage, and The Exonerated at Riverside Studios. Film credits include "Blood Diamond."

Lloyd was last represented in the West End by his production of Piaf that transferred from the Donmar Warehouse to the Vaudeville.

As an associate director, his credits include Michael Grandage's productions of Guy and Dolls at the Piccadilly Theatre and in Melbourne, Australia, and Evita at the Adelphi Theatre.
