At the time of it's release, "The Exterminator" was haunted by controversy. Several minutes of footage wound up on the cutting room floor due to pressure from the censors.
Director Glickenhaus says "Scenes which didn't make the film were ones that were political in nature. It was a time when certain countries had prohibition against showing films where 'bad guys' did not receive justice or didn't come to a bad end. The DVD release is the director's cut.
When movies are made, scenes are often
left on the cutting room floor.
Sometimes, there will be several versions
of a movie floating about on cable, tv or video etc. Other times, a Director may
release a special cut of the movie.
