Isla Blair and Nicholas Day will join the previously announced Tom Ellis, Katy Secombe, Charlotte Randle and Ben Aldridge as the parents, Rita and Ben Lyons, who the play revolves around. Those roles were originated on Broadway by, respectively, Linda Lavin (Tony-nominated for Best Performance by a Leading Actress in a play) and Dick Latessa. 

In the play, the Lyons family have gathered around the hospital bed of their dying father Ben. But surface compassion soon gives way to bickering, sniping and betraying each other's secrets.

Blair, who plays Rita Lyons, is a veteran stage actress whose credits include A Funny Thing Happened on the Way to the Forum (both the original West End production and the National Theatre revival), and, more recently, West End runs in Collaborators (at the Duchess) and The History Boys (at Wyndham's), the U.K. tour of Steel Collaborators and The Breath of Life at Sheffield Crucible. On TV she is well known for "House of Cards" and most recently appeared in BBC's "Single Father."

Day, who plays Ben Aldridge, has appeared in Cardenio and The City Madam (both for the RSC), The Iceman Cometh (at the Almeida and Old Vic), Dealer's Choice and the David Hare Trilogy (all at the National). TV credits include "Rosemary and Thyme," "Doc Martin," "New Tricks" and "Minder."  Films include "The Wolfman" and "Amazing Grace."

Mark Brokaw, who directed the previous incarnations of The Lyons both off and on Broadway, will direct a new production, with designs by Jonathan Fensom, lighting by Jason Taylor and sound by Gregory Clarke. Brokaw has previously directed Lobby Hero in both New York and London (at the Donmar Warehouse, subsequently transferring to the West End's Ambassadors Theatre). Other New York directing credits include Broadway's current Cinderella, This Is Our Youth, As Bees in Honey Drown and How I Learned to Drive. Nicky Silver's other plays include Pterodactyls, The Eros Trilogy, The Food Chain, Fat Men in Skirts, Fit to Be Tied, The Maiden's Prayer, Free Will and Wanton Lust, My Marriage to Ernest Borgnine, The Altruists and Raised in Captivity.
