Matt Smith has only just taken the reigns of the title role in 'Doctor Who' and he is already slated to make a guest-appearance on the spin-off series 'The Sarah Jane Adventures,' according to the BBC Press Office. For those unaware, the spin-off follows the adventures of former 'Doctor Who' companion Sarah Jane Smith as played by Elisabeth Sladen.

Also joining them in the same episode is former 'Doctor Who' companion Jo Grant. She'll be played by Katy Manning, who is stepping into the role for the first time since 1973.

And to round out the news trifecta, the episode will be written by the creator of 'The Sarah Jane Adventures' and the man responsible for bringing 'Doctor Who' back to television, Russell T. Davies. This would mark Davies' first time writing for the character of the Doctor since he left the series (and it could be argued that it's his first time writing for Smith's Doctor).

Mind you, Davies writing was never particularly impressive on the series in terms of science fiction. Davies' strength tends to be writing about relationships, and having the Doctor in a room with two of his ex-companions (which for the Doctor would be the equivalent of ex-girlfriends) is enough reason to tune in.

Doctor Who fans can once again rejoice. Episodes of the classic series are now available on YouTube. These are officially sanctioned by the BBC, so there's no piracy in this instance.

In this case, it's a selection of a single episode from four of the ten existing Doctors. There is The Edge of Destruction with William Hartnell, The Krotons with Patrick Troughton, Carnival of Monsters with Jon Pertwee and The Caves of Androzani and The Twin Dilemma with Peter Davison and Colin Baker, respectively.

Classic episodes have been available online before. Netflix had a few in their library for subscribers. This is the first instance I recall in which the episodes are available to anybody in the world at any time.

I note that a bunch of the available stories are written by the fantastic Doctor Who scribe Robert Holmes. This guarantees quality writing to compensate for the poor special effects of the era. Enjoy!
