When I was sixteen, I did a week’s work experience on the set of the Harry Potter films. They were filming Harry Potter and the Deathly Hallows Parts I and II, and I was in the costume department. It was the most exciting thing that had ever happened to me.
I signed a nondisclosure agreement and was taken inside. A member of the film crew generously gave me a tour of the most impressive sets. As everyone knows if they’ve gone on the Harry Potter Experience, the studios are on a former airfield near Watford, and the place is huge. The central hangar was vast, filled with portakabins and extensions and offices and film-sets. And the hangar was only part of the sprawling Harry Potter complex. Hundreds and hundreds of people worked there. Nobody took much notice of an overawed teenage boy.
