The first set of plays is One for the Road, Mountain Language and The New World Order, directed by Jamie Lloyd, and Ashes to Ashes directed by Lia Williams. Running from 6 September to 20 October the cast will include Paapa Essiedu (Hamlet) and Maggie Steed (Chewing Gum). They play in rep with The Lover and The Collection featuring the previously announced David Suchet and John Macmillan.

Joining Tamsin Greig in Landscape and A Kind of Alaska (25 October to 8 December), will be Keith Allen (Kingsman: The Golden Circle), whilst Rupert Graves (Sherlock) joins Jane Horrocks, Emma Naomi and Nicholas Woodeson in The Room, Victoria Station and Family Voices (13 December to 26 January), directed by Patrick Marber.

John Simm and Gary Kemp join the cast of Party Time and Celebration which run from 20 December to 26 January. Directed by Lloyd, the cast also features Phil Davis, Celia Imrie, Tracy-Ann Oberman and Abraham Popoola.

Lloyd will also direct a charity gala of Pinter's sketches, monologues and poems to celebrate Harold Pinter's birthday on 10 October, with all-star casting to be announced.

Also announced today, continuing their commitment to developing a new, more diverse West End audience, The Jamie Lloyd Company is offering 25,000 tickets across the season for £15 for people aged under 30, key workers and those receiving job seekers allowance.

Essiedu said: "25,000 good seats for £15 will provide meaningful access to Pinter's work for new theatregoers who may never have experienced the power of his work before. I feel certain that Pinter, the working-class boy from Hackney, would have approved."
