This little made for TV film is by no means an amazing film but to a young boy watching it one Friday afternoon during one of the fantastic 'Broom cupboard matinees' it opened his eyes to the possibilities of sci-fi cinema. The best thing about it is that it doesn't succumb to the idea that all sci-fi has to be special effects and explosions. Ahead of its time but unfortunately low on budget and probably lost in some BBC archive somewhere, if you saw it you loved it but you probably didn't and never will. Shame, Iā??d love to see it again!
