The version of this episode that in the Season One Box Set is the original edit that was only broadcast once (and only in a few areas of the US) during the series run, and is rarely seen on TV to this day. This version has a beginning montage that's mostly made of footage taken from various films. It is without the voice-overs that is in the more widely seen broadcast version, is way more violent, and has a number of on-screen deaths. Kellogg's, the series sponsor, had the producers replace this montage with a less violent one using more footage from different episodes of Season One.
