Until a dusty vidotape of 'All That Glitters', the 'missing' eightieth episode of the original series, turns up in someone's basement. The tape has degraded over time, obviously, so it's all a bit murky. Uniquely, there's a momentary glimpse of some text before the beginning titles that reads 'made in AfterEffects'; even experts on 1960's television production techniques are unable to definitively explain the significance of that. As a clever stylistic device, they only shot the actors from the neck down in this episode so the main cast aren't recognisable, and the soundtrack has sadly been lost. New tunics were specially commissioned for just this episode, and coincidentally they bear some similarity to modern replicas (though they obviously aren't). But there is one scene where the recently discovered fifth hero phaser is very clearly seen in close up, velcro and all. Interestingly for TV historians, Desilu were obviously experimenting with early subliminal imaging at the time, since there are also a few frames spliced in just before and after the appearance of the phaser - too few to be noticeable to the viewer - with the tantalisingly obscure words 'It's real'. The tape will up for auction soon with a starting price of $1 million, as befits such an iconic piece of cultural history.
