Playbill has news of a musical adaptation of Matilda for the RSC:
Roald Dahl’s popular 1988 children’s story Matilda will be adapted into a new musical. Tony-winning director Matthew Warchus will stage the production for the Royal Shakespeare Company, which will premiere at Stratford-upon-Avon’s Courtyard Theatre in winter 2010. The show will feature a book by playwright Dennis Kelly… and music and lyrics by Australian comedian, actor and musician Tim Minchin.
I suppose this could be interesting, depending on how the book and score turn out. Matilda is not one of the Dahl books I know well; in fact, I’ve never read it and only know the story from the film.
