Austin gave an interview about working on the play, stating - "My main aim for the show was to create something magical. With Harry Potter and the Cursed Child, the primary desire from everyone involved was to use traditional theatre craft and techniques but push the boundaries as to what we thought was possible. We needed to produce something mesmerising and create the world of illusion that the audience would expect from Harry Potter".
