Last Saturday night yet again there was another brilliant episode to be watched but the appearance of a certain someone really livened up the episode. Who was this person? well of course it was the one and only John Simm. Although John only appeared at the end of the episode he will in fact be a guest start in the final two episodes of Doctor Who. John Simm plays The Master who was a recurring character in the classic series of Doctor Who and has just been brought back. If you did happen to miss John appear then there is a video below of John's first shots on screen for Doctor Who.
