Wax trades on her image as a brassy American in her multiple television series, among them “Ruby”, “Hot Wax” and “Ruby Wax Meets”. She also co-wrote and starred in the television comedy series “Girls on Top” alongside Dawn French and Jennifer Saunders. The play tells of a seven year-old boy, his grandmother and their battles with a coven of witches. The Grand High Witch’s plans to rid England of children include changing them all into mice via poisoned chocolate. Like Mary Poppins, the show has been declared suitable only for children above the age of seven.

The cast is led by Wax and Dilys Laye as the grandmother, and also includes Giles Cooper, Isabel Ford, Chris Hawley, James Hirst, Peter Holdway, Katerina Jugati, Camilla Mathias, Keith Saha and Catherine Skinner, Simon Higlett designs, Mark Jonathan supplies the lighting, sound design is by Paul Groothuis, Matthew Scott is the show’s composer and Jenny Arnold choreographs. Also on-board is illusions director Paul Kieve, who worked as magic tutor Daniel Radcliffe on the “Harry Potter” films. Jonathan Church directs David Wood’s adaptation.

Press night at the Wyndham’s is on March 9. Before that, though, the production will tour the UK (without Wax, who will only play London) from Jan. 19. Venues include the Richmond Theatre, Salford’s Lowry Centre, Brighton’s Theatre Royal, Cardiff’s New Theatre, Stoke’s Regent Theatre and Nottingham’s Theatre Royal. After the London dates the tour continues to Belfast’s Opera House, the New Wimbledon Theatre, Southampton’s Mayflower Theatre, Plymouth’s Theatre Royal, Woking’s New Victoria Theatre, Norwich’s Theatre Royal, Oxford’s Playhouse, the Wolverhampton Grand, the Milton Keynes Theatre, Glasgow’s Theatre Royal and Bromley’s Churchill Theatre.
