Collars Up is New York based film collective that made films from 2003 until 2010. The films (with a few exceptions) were completely improvised usually starting with a location or prop and then coming up with the story and dialog completely on the fly. The films were directed and edited by Alan William Harris and featured core players Becca Greene, Marci Clark, Mackenzie Condon, Eric Hollerbach, and Will Nunziata with special guests along the way.
