There were two TV programmes which always used to make me hide behind a cushion on the sofa. One was, of course, Dr Who and the other was certain episodes of Sapphire and Steel. There was an episode of the latter which involved people have blank faces, stealing them from photographs. I just remember it was well scary. Joanna Lumley has certainly progressed from this and the New Avengers to Absolutely Fabulous and traveling around Asia on a train!
