Jay McGuiness will star as Josh Baskin. The actor, who was part of the boy band The Wanted, originated the role at the Theatre Royal Plymouth in 2016.
With music by David Shire and lyrics by Richard Maltby, Big The Musical has a book by John Weidman and direction and choreography by Morgan Young.
The musical concerns 12 year-old Josh Baskin, who longs to be big. When a mysterious Zoltar machine grants his wish, he finds himself trapped inside an adult’s body and is forced to live and work in a grown-up world, but his childlike innocence has a transforming effect on the adults he encounters.
The creative team also includes associate choreographer Helen Rymer, musical supervisor Stuart Morley, set and costume designer Simon Higlett, lighting designer Tim Lutkin, video designer Ian Galloway, and sound designers Terry Jardine and Avgoustos Psillas.
Based on the Twentieth Century Fox film written by Gary Ross and Ann Spielberg, Big will be produced in London by Michael Rose, Damien Sanders, and Paul Gregg for Encore Theatre Productions Limited.
