Franz, who plays Halie, is a Tony-winning Broadway veteran who has appeared in revivals of Brighton Beach Memoirs, Death of a Salesman and Long Day's Journey Into Night.

Brendan Coyle, who won an Olivier Award for The Weir, will take on the role of Tilden, with Sam Troughton playing the part of Vince, the son who returns to a house of half-crazed relatives.

Matthew Warchus (Life x 3, Our House) directs the first major London production of the darkly, comic drama in over 20 years.
