In the Victorian era, the heyday for popular theatre, audiences loved melodrama, spectacle and sensational scenes. “Sensation is what the public wants and you can’t give them too much of it,” said the highly successful actor, playwright and theatre manager Dion Boucicault. Plus ça change.

Harry Potter and the Cursed Child is not an adaptation of a novel by JK Rowling but a new play based on a story by her, Jack Thorne, the playwright, and John Tiffany, the director.

Harry is now an adult, aged 37, and he has a son, Albus, whom he sends to Hogwarts to be educated in wizardry. Albus’s best friend is Scorpius, son of Draco Malfoy, his father’s deadliest enemy. One of the major themes is about being a good dad. Just imagine what it would be like to be the son of Harry Potter. Parenting and growing up are already quite difficult enough.
