'The Stranger' was not dissimilar to the BBC's 'Doctor Who' and was probably inspired by everyone's favourite Time Lord, hitting Sydney TV screens the following year. Both appeared on the ABC. Well known Australian actor Ron Haddrick was a great choice for The Stranger as he had an other-worldly presence, not unlike, for example, Boris Karloff. I vaguely recall him appearing out of the mist but it's just so long ago, that's the limit of my memory.
