In this episode the two female race driver characters wear helmets in the colours of then currentWorld Champion Jim Clark, (Cynthia Quillan) and 1962 World Champion Graham Hill, (Teresa Montesini). This is so the studio shots could be edited into genuine race footage which is taken from the 1966 British Grand Prix at Brands Hatch.
John Hollis would again appear with Roger Moore as James Bond in the opening sequence of For Your Eyes Only as Blofield.
Race commentator is Robert Rietty in English mode.
