Adapted for the stage by Simon Stephens, The Curious Incident of the Dog in the Night-Time is based on Mark Haddon's 2003 best-selling novel about a fifteen-year-old math whiz who, despite his problems with social interactions, sets about investigating the murder of a neighborhood dog. The National Theatre production, a West End hit which won seven 2013 Olivier Awards including Best New Play, began performances on Sept. 10 at Broadway's Ethel Barrymore Theatre. Alex Sharp, Francesca Faridany, Ian Barford, Enid Graham, and Helen Carey head the cast. Marianne Elliott directs.
