Yes, apparently there really is a real life Quidditch World Cup these days. It is run by the International Quidditch Association (which is American, if you hadn’t guessed) and, among the hundreds of teams in the league, there is one from Iran.
I’m all for sport being a unifying activity, but I’m still a bit surprised that Iranians are interested enough to get involved. Nonetheless, there they are.
Sadly, there is no actual flying; instead the players run around with a broom between their legs. There’s a promotional video for the 2011 World Cup here.
