From founder of gonzo is John “Buttman” Stagliano.
“Gonzo can take on several different forms. It can vary from the cameraman (in adult, very often the director) interviewing the actors, or participating in the scene with dialogue and/or sex. It can also mean that the actors are simply acknowledging the fact that there is a camera shooting what they are doing. So, although in adult gonzo, the cameraman is usually somehow visible or audible, simply the actors playing to the camera constitutes a gonzo scene.”
