It’s as Yates said, lightning doesn’t strike twice. I think really one of the reasons that I think Harry Potter works is it’s culturally specific but it’s thematically universal. It’s about love and death and loss and friendship and loyalty and good versus evil. We all know characters like Harry, Ron and Hermione, we’ve all had teachers like Dumbledore or Snape or Lupin… We haven’t known too many Voldemorts, I hope. But these are people who are not… yes, they’re British, but I think they’re relatable to people all over the world.
