The National Theatre's production of The Curious Incident of the Dog in the Night-Time has welcomed a new cast to the West End production, and last night (30 June 2015) held a special gala performance with celebrity V.I.P. guests at the Gielgud Theatre.

The Curious Incident of the Dog in the Night-Time recently extended booking in London, releasing over 120,000 tickets and is now booking until 13 February 2016.

The Curious Incident of the Dog in the Night-Time, which started life at the National Theatre's Cottesloe Theatre in 2012, transferred to the West End in 2013 (winning seven Olivier Awards including Best New Play) and is now simultaneously running at the Gielgud Theatre in London's West End, on Broadway at the Ethel Barrymore Theatre and on tour in the UK and Ireland. The production has been hugely successful during this year's Broadway theatre awards season in New York, also winning 5 Outer Critics Circle Awards, including Outstanding New Broadway Play and 6 Drama Desk awards including Outstanding Play.

The new West End is led by Sion Daniel Young as Christopher Boone. He is joined byRebecca Lacey as Siobhan, Nicolas Tennant as Ed, Mary Stockley as Judy, Jacqueline Clarke as Mrs Alexander, Indra Ové as Mrs Shears, Stephen Beckett as Roger Shears,Matthew Trevannion as Mr Thompson, Pearl Mackie as No. 40/Punk Girl, Sean McKenzie as Reverend Peters and Kaffe Keating plays alternate Christopher. They are joined by Mark Rawlings, Penelope McGhie, Naomi Said and Simon Victor.

Christopher, fifteen years old, stands besides Mrs Shears' dead dog. It has been speared with a garden fork, it is seven minutes after midnight and Christopher is under suspicion. He records each fact in a book he is writing to solve the mystery of who murdered Wellington. He has an extraordinary brain, and is exceptional at maths while ill-equipped to interpret everyday life. He has never ventured alone beyond the end of his road, he detests being touched and distrusts strangers. But his detective work, forbidden by his father, takes him on a frightening journey that upturns his world.
