Full casting has been announced for a new production of Eugene O’Neill’s autobiographical magnum opus Long Day’s Journey into Night, which begins previews at London’s Wyndham’s Theatre on 19 March 2024.

Directed by Jeremy Herrin, the play will star Golden Globe and Emmy award-winning actress Patricia Clarkson (Sharp Objects) as matriarch Mary Tyrone, alongside Alex Lawther (The End of the F***ing World, Black Mirror) as Edmund, BAFTA award-nominee Daryl McCormack (Bad Sisters, Good Luck to You, Leo Grande) as James Jr, and Louisa Harland (Derry Girls) as Cathleen. They join Emmy award-winning actor Brian Cox (Succession) who plays James Tyrone, in his first West End role in almost a decade. 

Often regarded as the greatest American play of the 20th Century, O’Neill’s Pulitzer Prize-winning piece depicts a summer day in the life of the Tyrones, closely based on O’Neill’s own dysfunctional family. Moving and inspiring in equal measure, O’Neill’s masterpiece is a compelling story of love, hate, betrayal, addiction and the impossible fragility of family bonds.

Following his recent acclaimed production of Best of Enemies, Jeremy Herrin’s new production will bring into sharp focus the universality of O’Neill’s beautifully crafted characters and language. Long Day’s Journey into Night is designed by Lizzie Clachan, with further creative team to be announced.

Jeremy Herrin said: “A great play is always relevant and Long Day’s Journey Into Night is, it’s often argued, the greatest play of the 20th Century. With its searing honesty and blistering depth of emotion, it must be up there.

“What is impossible to argue with is that we have the best cast and, in Lizzie Clachan, one of the most exciting designers in the country, to discover what makes O’Neill’s masterwork relevant for now. 

“I can’t wait to bring this classic to life. I anticipate a feast of fine acting and vivid performances in what I hope to be a high definition production.”
