Improv Everywhere and its fans have been putting on crowdsourced public stunts for more than ten years. Now, a documentary feature offers viewers a look inside at the life of the world’s most numerous performance group. It’s called We Cause Scenes, and it’s available for purchase from iTunes.

We Cause Scenes is a look inside the mind of Improv Everywhere founder Charlie Todd, who has spent the past decade freezing in train stations, riding the subway without pants, and reenacting his favorite movie scenes. The film also examines the thousands of confederates who help make each ‘prank’ a success. A trailer released on January 7th has drawn a significant amount of attention on YouTube.

We Cause Scenes debuted at South By Southwest in April 2013, and then toured the country for the rest of the year. It’s now offered for the masses at both iTunes and its own VHX-powered website, but it comes with a hefty price tag of $12.99. Clearly, Improv Everywhere is hoping its diehard fans will pay whatever it takes to own the movie, even if casual fans won’t be convinced to pick it up.

The We Cause Scenes website promises more screenings in 2014, so even if you don’t have $13 to shell over to Todd and his gang of pranksters, you may still have an opportunity to view the film. Of course, Improv Everywhere’s main export–its public stunts–will still be available on its YouTube channel, so be sure to keep an eye there to see how they cause a scene next.
