This Saturday, the new K9 will appear on the next episode of Doctor Who and then, very soon, the eminently merchandisable robo-dog will have his own spin-off series, part live action and part CG, co-produced by the BBC and Jetix. So much for public broadcasting not been commercialised.
Also appearing on the next Who is Antony Stuart Head. If what I've heard is true, he's playing The Master, the Doctor's nemesis. Previous epsiodes claimed that all other Time Lords were dead now, so if The Master does crop up, then this post will have tunred out to be loaded with very major spoiler material.
