BBC Wales and BBC Drama has announced that Bafta and Hugo Award winning writer Steven Moffat will succeed Russell T Davies as Lead Writer and Executive Producer of the fifth series of Doctor Who, which will broadcast on BBC One in 2010.

So, the much rumoured departure of Russell T Davies has finally happened. After the triumphant and poignant end of series two, I certainly would’ve looked upon his departure with horror. However, we are now part way through series four, and despite the fantastic kick-off with ‘The Fires of Pompeii’, I believe it is the right time for Davies to step down. The reason: quite simply, the subsequent episodes have somewhat failed to deliver. ‘The Sontaran Strategem’ and the ‘Planet of the Ood’ were of a slightly higher calibre than the rest, but they were followed by the truly awful ‘The Doctor’s Daughter’ - “Hello Dad!” …ouch - and the painfully plotted ‘Unicorn and the Wasp.’ I’m not going to go into specifics about these episodes, but in both, the usual well crafted balance between slightly unbelievable plot, action, characterisation and great one-liners was woefully askew. There is now real evidence that the show is relying on ‘formula’ and is in danger of becoming a glib parody of itself.

Still, on 31st May and 7th June 2008 on BBC One, we are to be treated to Stephen Moffat’s ‘Silence in the Library’ two parter, which coming from a writer of his pedigree, should hopefully lift the series when it needs it the most. Moffat has penned some of the series’ most unforgettable and acclaimed episodes - including the Series One two-parter ‘The Empty Child,’ which became famous for its terrifying refrain “Are you my mummy?” earning him his first Hugo Award (his second for The Girl in the Fireplace for Series Two) and ‘Blink’ with its terrifying Weeping Angels, for which he was awarded the 2008 Bafta Writer Award.

There is no doubt that Moffat will bring a much needed darker aspect to the franchise, when he takes over for series five. I’m fervently hoping he is in time to save the series, that is only now showing signs of flagging. And who knows, he might bring with him a new Doctor. I hope so…

iPlayed the BBC4 programme about the blokish love affair for all things Gerry Anderson last night. A wonderful nostalgia trip back to the early sixties, the programme kicked off with ‘Super Car’ (in those days they apparently used condoms to make the mouths move - cue boyish humour in the chemists) before moving on the Fireball XL5, Stingray, Captain Scarlet and Joe 90. But of course, the star of the show was Thunderbirds - at its zenith in the late 1960s, the puppet-based action series was the most expensive TV programme ever produced in Britain.

It’s quite amazing to think that in their little workshop in Slough, they were the world leaders in special effects (all before CGI). And I don’t think I’m being too misty-eyed to state that the FX still stands up today. If anything, my love affair with Thunderbirds has grown stronger over the years. As a kid, I loved the explosions and the gadgets (and still do), but it is testament to the wonderful plots and an almost cinematic approach (Anderson was a frustrated movie maker) that has allowed Thunderbirds to endure over the years.

Interestingly, the shows were originally planned for only half an hour, but Lou Grade insisted that they be the full sixty minutes. This led to character development that was, at first, ‘filling’ for the seven episodes that had all ready been completed, but became the mainstay of the show’s enduring appeal.

The show’s special effects team split up after Thunderbirds and went on, in their individual capacities, to become the head of the BBC special effects unit, work on Alien and Terminator and have long lives spent in the movie industry.

For me? Well, I still get a shiver of unabridged wonder when I see Thunderbird 2 and hear that fabulous soundtrack - and it was all done with puppets…marvellous!

Interesting Stuff:

• If you look inside the hangar of Thunderbird 1, there is clearly a lemon squeezer glued to the wall.
• The enduring problem of using puppets was that they couldn’t get them to walk convincingly. Cue a whole range of gadgets to overcome this problem.
• “I wasn’t really interested in the plot, I just wanted to get to the vehicles and the explosions as quickly as possible.” Nick Park, the creator of Wallace and Gromit.
