In my opinion, one of the top series of this genre ever produced for television, the original TZ aired from 1959 to 1964. Rod Serling invited viewers to submit a script. He was flooded with over 14,000, and actually got around to reading 500 of them, but only two were any good, and he couldn't use them because they didn't fit with the format of the show. CBS originally wanted Orson Welles as the narrator/host, but the producers felt that he asked for too much money. I just can't imagine anyone but Rod Serling narrating this series, it was his baby from the start. He made up the phrase 'Fifth Dimension' to use in one season's opening narration, stating that he wanted to go one beyond the four known dimensions. A reporter once asked him what the fourth dimension was, (given the first three are length, width, and height). Serling supposedly answered, 'I don't know. Aren't there four?' Hey, if he thought so, that would have been good enough for me!
