What would you think if you were hanging out at your local mall and all of a sudden some of the people stop having their meals and start dancing together as if they were on a musical? Is it a new hit from the New Radicals? Not quite, those guys haven’t done anything since 1999. Chances are you are being part of one of the ImprovEverywhere scenes. This New York-based collective of actors and volunteers are set out and about to generate scenes of chaos and joy in public places; in order to do this, they require something from 5 to 200 ‘agents’ or undercover volunteers. The idea is that the happenings have to look spontaneous to the rest of the people, so that they are secretly taped and then posted on the site. By visiting ImprovEverywhere.com, you can learn about the latest projects and also take a look at other happenings that have happened in the past; you can find videos, pictures and a detailed explanation of what they did, how they managed to stage it and lots of comments on how people reacted. If you live outside NY or even outside of the US, make sure to check out the ‘global’ area to find the group from your city and start spreading the scenes around the world.
