mudbloodsHeated rivalries, tough tackles, team pride ... they're all coming to a big screen near you. And no, we're not talking about a replay of the FIFA World Cup final. We're talking about the Quidditch World Cup!

You might be scratching your head and thinking: Quidditch, the fictional game from "Harry Potter"? Yup, but it's not fictional at all; people play it in real life! And the documentary "Mudbloods" follows the UCLA team as they head to the Fifth Annual Quidditch World Cup in New York City to pursue the big trophy.

A new trailer for "Mudbloods" addresses full-on the disbelief that follows the game. "You get two questions: How does the Snitch work, and how do you fly?" says one player.

The sport was invented by J.K. Rowling, but students at Middlebury College adapted into a real-life sport and it caught on at colleges across the country. (It was also featured in the Vince Vaughn-Owen Wilson comedy "The Internship.")

As one player passionately declares, "We want to compete and we want to show you that this is real."

We believe.
