What's done cannot be undone' Three weird sisters, an eerie prophecy and a lust for power start a spiral of betrayal which has disastrous consequences. Primary Classics, produced by the National Theatre's Discover programme, aims to introduce children aged 7 to 11 to Shakespeare. This version of Macbeth, adapted and originally directed by Carl Heap, preserves the core of Shakespeare's plot, retains the original langauge, yet is presented very much with the target age group in mind. Carl Heap's introduction will help readers, teachers and practitioners alike to imagine or produce their own version.
