The production will open at Theatre Royal Plymouth from 1 to 15 April, followed by a week at The Lowry, Salford from 25 to 29 April, and finishing at Bord Gais Energy Theatre, Dublin from 2 to 13 May, prior to a West End run.

SLEEPLESS is the enchanting new romantic musical comedy based on the original story and screenplay of the movie classic Sleepless In Seattle. Like the much loved movie, SLEEPLESS tells the heart-warming tale of Sam, who moves to Seattle with his eight year-old son, Jonah, following the tragic death of his wife. When Jonah phones a radio show, Sam is forced to talk about his broken heart and sleepless nights live on air, and he suddenly finds himself one of the most sought after single men in America and a great news story for feisty journalist Annie on the opposite side of the country. A fresh and lively book alongside a brand-new musical score bring this most timeless of romantic comedies to life on stage.
