Season 1 had Daleks, Season 2 had the Cybermen, so it makes sense Season 3 has the Master right? Well apparently so as the Sun, Metro and the Independant report John Simm of Life on Mars is to play the Master. (Also purely by coincidence a Master boxed set of Tom Baker/Peter Davidson episodes has just been released).
This means there have been (arguably) six people to play the Master:-
Master 1 - Roger Delgado, moustache twirling Bond villain.
Master 2 - Peter Pratt, zombie with pingpong eyes.
Master 3 - Geoffrey Beevers, still a zombie but played by someone else
Master 4 - Anthony Ainley, moustache twirling pantomine villain.
Master 5 - Eric Roberts, of the McGann movie
Master 6 - John Simm?
Also, Mister Saxon is an anagaram of "On Master Six".
Cunning eh? And yet, given the lack of sophistication Bad Wolf and Torchwood metaplots I suspect this is too clever by half and probably not true. But it's scarily coincidental nonetheless...
