Improv Everywhere (often abbreviated IE) is a comedic performance art group based in New York City, formed in 2001 by Charlie Todd. Its slogan is "We Cause Scenes". The group carries out pranks, which they call "missions", in public places. The stated goal of these missions is to cause scenes of "chaos and joy." Some of the group's missions use hundreds or even thousands of performers and are similar to flash mobs, while other missions utilize only a handful of performers. Improv Everywhere has stated that they do not identify their work with the term flash mob, in part because the group was created two years prior to the flash mob trend, and the group has an apolitical nature. While Improv Everywhere was created years before YouTube, the group has grown in notoriety since joining the site in April 2006. To date, Improv Everywhere's videos have been viewed over 470 million times on YouTube. They have over 1.9 million YouTube subscribers. In 2007, the group shot a television pilot for NBC. In May 2009, HarperCollins released a book about Improv Everywhere, Causing a Scene The book, written by founder Charlie Todd and senior agent Alex Scordelis, is a behind-the-scenes look at some of the group's stunts. In 2013, a feature-length documentary about Improv Everywhere premiered at the South By Southwest Festival in Austin, Texas. The film, titled We Cause Scenes, was released digitally on iTunes, Netflix and other platforms in 2014. In 2019, Improv Everywhere produced the Disney+ live-action series Pixar In Real Life, which premiered on 12 November 2019, with twelve episodes set to release monthly. Background After graduating from the University of North Carolina at Chapel Hill, Todd started the group in August 2001 after playing a prank in a Manhattan bar with some friends that involved him pretending to be musician Ben Folds. Later that year Todd started taking classes at the Upright Citizens Brigade Theatre in New York City where he first met most of the "Senior Agents" of Improv Everywhere. The owners of the theatre, The Upright Citizens Brigade (UCB), had a television series from 1998–2000 on Comedy Central. While primarily a sketch comedy show, the UCB often filmed their characters in public places with hidden cameras and showed the footage under the end credits. Both the UCB's show and their teachings on improv have been influential to Improv Everywhere. Todd currently performs on a
