From http://www.ImprovEverywhere.com, 16 agents create a spontaneous musical in a food court in a Los Angeles mall. Using wireless microphones and the mall's PA system, both their voices and the music was amplified throughout the food court. All cameras were hidden behind two-way mirrors and other concealed structures.
This is one of over 70 different missions Improv Everywhere has executed over the past six years in New York City. Others include Frozen Grand Central, the Best Buy uniform prank, and the famous U2 Rooftop Hoax, to name a few. Visit the website to see tons of photos and video of all of our work, including behind the scenes information on how this video was made.
I was powerful distracted by the moment when the woman shakes the "baby" - wish they hadn't done that. Otherwise, wonderful!
