Where in the Hell Is the Lavender House? The Longmont Potion Castle Story

Two filmmakers attempt to make a documentary about an anonymous phone-work artist called Longmont Potion Castle who's been releasing albums of surreal and hilarious pranks for over thirty years. In spite of a semi-successful crowdfunding campaign and the involvement of celebrity fans, the filmmakers succumb to their own infighting and bad luck leaving an unpaid camera operator to finish the film.
