Coming to On Demand and a limited theater release in October is Mudbloods, a documentary about the real-life Quidditch clubs popping up all over college universities. It's both endearingly earnest and unquestionably weird, but there is something undeniably compelling about this level of devotion.
Mudbloods follows in the long tradition of geek documentaries like Trekkies or King of Kong, which walk the line of appreciation and ridicule. From the official website:
Transforming Harry Potter's fictional competition into a physically demanding, real-life sport, Quidditch has secured its place as one of the fastest growing collegiate club sports today. MUDBLOODS follows the resilient underdogs of the UCLA Quidditch team as they make their way to the Fifth Annual Quidditch World Cup in New York City. Through nail biting victories and losses, the dreamers, creators and athletes who make up this exceptional community come together to make this magical sport into something you could've never imagined, until now.
It's like an underdog sports film, only a documentary and about Quidditch.
