This teaser was originally placed at the end of the unaired pilot, THE CRASH, just prior to the end credits. Once ABC decided to broadcast episodes out of production order, this teaser may have been deemed unusable and never broadcast. When the unaired pilot was released on DVD this teaser was omitted. Dick Tufeld is the announcer.
I captured the audio from an old VHS recording, and then restored the image by sourcing various clips from the DVD release.
Part of this preview was from the episode The Weird World,the 2nd story to be shot,but set back for later which is a shame as it's,I feel,one of the best.There were supposed to be human bones around the spider's web,ABC censors said No Way to that.Contrast that decision to what they show on tv today,say Walking Dead-how things have changed,not for the better.
