Sam Mendes' production of Charlie and the Chocolate Factory has extended its run at Theatre Royal Drury Lane to 1 November 2014.
Today also sees the launch of the official cast recording album, featuring the entire cast including Douglas Hodge as Willy Wonka. It contains every number from the show, including "Pure Imagination", "Must Be Believed to Be Seen" and "Almost Nearly Perfect".
The show, which opened in June, is based on Roald Dahl's classic children's novel and centres on mysterious sweet-maker Wonka, who is opening his Chocolate Factory for just one day, and the humble boy Charlie Bucket for whom it promises to be a mouth-watering chance to feast his eyes on sweets beyond his wildest imagination.
The production has currently been seen by almost 300,000 people since opening, and the extension sees the release of almost 400,000 extra tickets.
The musical has a book by David Greig and new songs from Marc Shaiman and Scott Wittman, whose credits include the Tony Award-winning Hairspray.
Set and costume design is by Mark Thompson with choreography by Peter Darling (Matilda, Billy Elliot). Other members of the creative team include: Doug Besterman (orchestrations); Nicholas Skilbeck (music director); Paul Pyant (lighting designer); Paul Arditti (sound designer) and Jon Driscoll (video and projection designer).
