Joining the previously announced Orlando Bloom (as Steven) will be Lynda Baron (Mrs. Burnett), Gareth Farr (Colin), Paul Hilton (Andrew) and Ciaran McIntyre (Reardon). Anna Mackmin will direct the production, which begins previews July 5 at the Duke of York's Theatre with an official opening July 12. Produced by Sonia Friedman Productions, the play is currently booking until Sept. 15.

In Celebration will feature designs by Lez Brotherston, lighting by Mark Henderson, music by Stephen Warbeck and sound by John Leonard.

The play, according to press notes, is described in this manner: "Three brothers — Andrew, Colin and Steven — return home to the northern roots of their childhood for a family reunion. Although they have returned to celebrate, the explosive complexities of family life and long-held grievances are unlikely to improve the chances of a decent party."

Lynda Baron is best known for her role as Nurse Gladys on the BBC series "Open All Hours." Her theatre work includes The Full Monty, I Am Yours, An Inspector Calls, Stepping Out and Follies.

Gareth Farr's theatre work includes How Many Miles to Basra, The Long and the Short and the Tall, Harvest, Romeo and Juliet and Hobson's Choice. He has also been seen on television in "A Life Beyond the Box," "Turkish Delight" and "Jonathan Creek." Paul Hilton's theatre credits include The Wild Duck, Mourning Becomes Electra, The President of an Empty Room, Three Sisters and The Oresteia. On TV he has been seen in "True Dare Kiss," "The Belsen Redemption," "Dalziel and Pascoe," "Medieval Heist" and "Trial and Retribution XIII."

Ciaran McIntyre's theatre work includes The Taming of the Shrew, The Shadow of a Gunman, Coriolanus, Richard II, The Lieutenant of Inishmore and The Quare Fellow; his TV work includes "The Time of Your Life," "Gideon’s Daughter," "Doctors," "Hippies" and "Absolutely Fabulous."

In Celebration received its world premiere at the Royal Court Theatre in 1969.
