Dahl's Matilda turned into a musical by the Royal Shakespeare Company

Matilda is one of Roald Dahl's most popular stories.

It is a dark tale of a clever young girl with clueless and unpleasant parents.

It has already been brought to life on film and has now been turned into a musical by the Royal Shakespeare Company who got the comedian and song-writer, Tim Minchin to adapt the story for the stage.
