Roald Dahl's most treasured tale is coming to the land where sweet dreams come true- Broadway- in a delicious new musical! Willy Wonka, world famous inventor of the Everlasting Gobstopper, has just made an astonishing announcement. His marvelous- and mysterious- factory is opening its gates... to a lucky few. It's a world of pure imagination.

And who better to conjure up this confectionary wonder than three-time Tony Award-winning director JACK O'BRIEN, the Grammy and Tony-winning songwriters of Hairspray, Marc Shaiman and Scott Wittman, and internationally acclaimed playwright DAVID GRIEG. Audiences around the world have long adored the best-selling book and films, but none have experienced the magic of Wonka quite like this- until now.
