I just watched this movie again for the first time as an adult. I couldn't believe why I thought this movie was so good when I first saw it as a kid on HBO. The collars that are used are the exact same ones that were used in the opening sequence of "The Running Man" (same look, same design, same result, etc.,). I remember the black trustee in the movie from "Return of the Living Dead III". I guess I was using kid logic at the time; exploding heads=good. Rutger Hauer seems to be a veteran of this type of movie in recent years. He's kind of like that guy from the "American Ninja" movies or any movie from now defunct Cannon Pictures. If you want to see a truly good movie with Rutger Hauer in it, get some of his earlier Dutch films, Wolfgang Peterson's "Flesh and Blood" and, my personal favorite "Blind Fury.
