This is a compilation of unrelated scenes featuring the late John C. Holmes, and his incredible 13-inch schlong. (This compilation is vastly superior to another John Holmes compilation DVD that I review on this site)
Some of the scenes are from Holmes' Johnny Wadd series from the 1970s, directed by Bob Chinn. The plot and acting from the scenes included in this compilation makes me wish that the whole Johnny Wadd series would be rescued from the vaults and re-issued on DVD. I imagine that most of these movies simply no longer exist, which is too bad.
A couple of years ago, Bob Chinn tried to re-start the Johnny Wadd series with a different actor. Unfortunately, there doesn't seem to be a market for expensive, plot-driven features with high production values. These types of movies are out-competed by the flood of much cheaper gonzo material that completely dispenses with plot, writing, acting, outdoor shots, indoor sets, etc. All the more reason why someone should re-issue stuff from the 1970s.
