Well remembered 6 week holiday TV for kids during the morning on mid1970s TyneTees in the UK. The main things I remember of the series are Platonius' side kicks were two glass heads who lit up when in conversation.Plus Space, Platonius' Base, which looked suspiciously like a studio cave on a planet of stock film of the Australian desert, and the Pheonix spaceship itself were amazingly dark either to create a menacing feel or it was so low budget that the creators of the show could only afford one light in the studio! If Mark is correct and the whole series remains in Australia, where is the DVD box set with extras!!
