Confirmed on tonight's broadcast of "The Next Doctor"... the next Doctor Who special will be Planet of the Dead, starring David Tennant. It will air at Easter 2009. More details when available.

The experts of Doctor Who have revealed some of the secrets behind the show, from making the TARDIS appear to shooting Cybermen. What's it like to work with Daleks? How do terrifying monsters come to life? What do you use to blast a Cyberman?

BAFTA teamed up with the London Children's Film Festival and the BBC to present a special event in front of 2,000 Doctor Who fans at the Barbican Centre, London, the highlights of which are now available online at the BAFTA website.

Inside the World of Doctor Who brought together the experts responsible for creating the series, from creating a universe of sound to animating a Slitheen or the Ood. With excerpts from the show and real props from the programme, this is an unmissable opportunity to experience what it's really like backstage at Doctor Who.

Watch presenter Kirsten O'Brien emerge from the TARDIS and welcome a range of special guests to the stage including members of the Doctor Who special effects team and the man behind it all - Executive Producer and Lead Writer, Russell T Davies.

BBC News reports that Doctor Who chief writer and executive producer Russell T Davies expects Tenth Doctor actor David Tennant to be fit enough to begin work next month on the first of the four specials which will end his tenure in the part.

Tennant is due to resume work on Doctor Who on the 19th of January, but has recently undergone much-publicised back surgery which forced him to pull out of several dates of the London run of his acclaimed starring role in Hamlet. However, speaking at the press launch for the Christmas special "The Next Doctor" today, Russell T Davies commented that he was hopeful Tennant would be fit to start work on schedule.

Davies did, however, comment that: "We'll have to be very careful. I don't think we'll be swinging him on a wire on his first day back." He did, however, add that no rewrites were expected to be needed to accommodate Tennant's injury.

The last week or so has seen odds on Paterson Joseph fall dramatically, with many bookmakers no longer accepting bets on the actor! As of today, Betfair are only offering 7/17! Both Den of Geek and Comic Book Resources suspect that he will soon be named. As reported earlier, the actor won't be drawn on his prospects, telling BBC News: "I'm afraid I can't make any comment on it. I'm not a gambler. And I don't approve of gambling unless it's for the Grand National."

Earlier in the month Colin Salmon (seen as Dr Moon in The Silence in the Library/Forest of the Dead) was also being considered by the media;Wiredsuggested that he would be announced on Children in Need, though in the end the only comment on potential casting was made by presenter Terry Wogan on David Morrissey's appearance in the Christmas Special preview. (Further Colin Salmon coverage from Now Magazine, What's on TV, Flick Filosopher and One India).

Michael Deacon from the Telegraph wasn't too keen on Paterson Joseph or David Morrissey as the Doctor, citing Rhys Ifans as his favourite for the role: "He can do funny. He can do charisma. He has a sense of danger about him. He looks good enough to appeal to kids and mums, and he's a serious enough actor to appeal to longstanding Whovians."

The Mirror reports on Spooks actor Rupert Penry-Jones, explaining why the role doesn't appeal: "I haven't been asked to take over in Doctor Who. I took over from someone in Spooks, and I was never quite comfortable with that... so I wouldn't like to take over something else. I'd like to stick with original things."

The Stage is running an occasional look at who could take on the role of the Doctor, and have so far covered Serenity and Inside Man actor Chiwetal Ejiofor,and Benedict Cumberbatch, seen recently playing Stephen Hawking in BBC's Hawking and Stephen Ezard in The Last Enemy. Writer Liz Thomas also considers women in the role.

The Coventry Telegraph has offered up two more choices for the Doctor, picked up from the Birmingham Memorabilia that took place last weekend.Warwick Davis (most recently seen as Professor Flitwick in the Harry Potter films) mentioned that he was interested in the role: "I had a great idea: Doctor Who is going to change, regenerate, but something goes a bit wrong. For just a couple of episodes it would be me as the Doctor, they go in the Tardis and inside it's not vast, it's tiny and they all bang their heads!" Meanwhile, former Davros performer Terry Molloy has a different suggestion: "My idea of the new Doctor is Liz Smith, who plays the grandmother ('Nana') in the comedy The Royle Family. I think we ought to have a really old, crabby woman. She'd be great. Like William Hartnell but female. She'd soon send the Daleks packing."

Other names bandied about in the media include James Frain (Herts and Essex Observer), Robert Pattinson (Chicago Tribune), Dexter Fletcher(Times), and Big Brother winner Pete Bennett (Daily Star). Further articles on casting from Digital Spy, RTD comments from Evening Post, John Simm doesn't want to be the Doctor from The Times, and no decision to be made until next year from tv.com.

Actor Paterson Joseph, the man held by many media reports to be one of the favourites to land the role of the Eleventh Doctor, has spoken to the BBC News website about the speculation surrounding his possible casting.

"His [the Doctor's] parameters are so vast. I don't see why he can't have more regenerations than the 13 that those who know think a Time Lord can have," he told the website. Joseph previously appeared in "Bad Wolf" and "The Parting of the Ways" as Rodrick, and the BBC reports that bookmakers are offering 3-1 odds on him becoming the first black actor to play the Doctor.

Joseph also claims to be a fan of the sci-fi genre, claiming that: "In no other genre can you be believable as an immortal character. I love sci-fi for that, so yeah - I'm a big fan."

As the 45th anniversary of the start of Doctor Who approaches, the BBC has put online an archive collection of documents and images detailing the programme's genesis.

It includes a 1962 report into whether the BBC should make a sci-fi drama, concept notes written in 1963 forming a summary of ideas for just such a programme, and background notes by C E Webber and Sydney Newman in which they outline the format for the new series that had been christenedDr. Who.

Presenter Terry Wogan has reported on his radio show that the next Doctor might be announced in this year'sChildren In Need show. Although nothing has appeared officially to confirm this, Wired suggests that such an announcement would be a good fund-raiser for the event.

David Tennant appeared on BBC's Breakfast on Monday, and during the interview indicated that he wouldn't rule out returning to the show at some point in the future. He also mentioned that Steven Moffat's appointment had almost swayed his decision to leave (something that he and Russell T Davies had agreed upon some months previously). On the inevitable subject of a good female contender for the role, he lightly suggested his former co-star Billie Piper.

Based on the interview, Den of Geek speculated on how he might return to the role, whilst the South Wales Echoconcentrated on the Piper connection - also noting that the odds from William Hill on a female Doctor had now been lowered from 20/1 to 12/1 after the interview. Meanwhile, Lucy Mangan of theGuardian commented on her husband's view of a female in the part and why she thinks it would be a good move for the show. (Other stories related to the Breakfast interview from BBC News, Reuters, Press Association, Wales Online, Telegraph, Daily Mail, Now,Melbourne Herald)

Meanwhile, speculation on who would take up the mantle continues apace in the media!

Back in 1999, DWM ran an article in which well-known fans at the time commented on how they'd like to see the Doctor return. One of those was new head writer Steven Moffat, in which he suggested an older actor for the role, a "grandfather" figure. In spite of a decade between this and the production of Moffat's series next year, this hasn't stopped The Sun from revitalising these anecdotes! (Story also taken up by MyPark Magazine and BBC America'sAnglophenia)

The Mirror reports that ex-EastEnders actor Tom Ellis is under consideration - Ellis was previously seen in the series as Tom Milligan in Last Of The Time Lords. (Story also taken up by RTE and Now)

More articles/references to Tennant leaving and other Who news in the media can be found in the dedicated Media Watch thread in the Doctor Who Forum.

After the announcement of David Tennant leaving, it was inevitable that the media would begin to speculate on who would assume the role of the Doctor in 2010. BBC Entertainment reporter Lizo Mzimba made a report on Tennant's departure which ran on BBC news programmes over the course of yesterday, citing Paterson Joseph(previously seen in the series as Rodrick in the Series One finale), David Morrissey (to be seen in the forthcoming Christmas special), and James Nesbitt as the leading choices.

Betting site William Hill have offered odds on a number of actors for the role (listed below); an article on their website has reported on how the odds on Welsh actor Rhys Ifans have been slashed following bets made in the Cardiff area! Says spokesman Rupert Adams: "So far we have not been able to find out where the rumours about Rhys are coming from but on paper we think he will make a good Doctor."

Today's Telegraph speculates on the top choices in more detail, also speculating onCatherine Tate - the possibility of a female Doctor once again suggested by Russell T Davies in an interview with Tate and Steven Moffat at the National Television Awards on Wednesday.

Another article appeared on BBC News's E24 entertainment programme last night, in which Lizo interviewed a few stars on their thoughts for who should be the next Doctor. Ricky Gervais put forward his usual collaborator Stephen Merchant for the role, Peter Purves and John Noakes suggestedthemselves(!), James Bond star Daniel Craig liked the idea of a woman, whilst singer Tom Jones agreed with the idea of fellow Welshman Rhys Ifans. As for David Tennant himself: "I’ve always been a big supporter of Wee Jimmy Krankie and I, you know, if it wasn’t me it was gonna be him, her, him. So the campaign starts here for me, to get wee Jimmy Krankie in the Tardis and big Ian Krankie as the companion. I think that works."

Other online media articles include: BBC News Northern Ireland, Londonderry Sentinel, Belfast Telegraph on James Nesbitt; Online Betting Guide; This is Swansea; BBC America; The Mirror; EW.Com Popwatch; LA Times.

Update: the Daily Mail places David Morrissey as favourite; BBC News adds Sean Pertwee and James McAvoyto the list; the Sun reports on reader ideas, including Harry Hill and Jonathan Rhys Meyers; and Russell Toveytells Digital Spy on his thoughts of being named as a possible Doctor.

David Tennant will be leaving Doctor Who at the conclusion of the 2009 specials currently in production, the actor announced live on stage this evening at the National Television Awards.

The Guardian newspaper this evening broke the story prematurely, reporting on their website (in a report subsequently pulled down) that Tennant is "vacating the TARDIS and leaving the BBC's Doctor Who series at the end of next year. Tennant's decision brings to an end his popular four-year tenure as the time lord." The article went on to say that the BBC had confirmed that the actor "would complete the filming of four special episodes to be screened this year and in early 2010, as well as 2009's Christmas special."

The BBC Doctor Who website has now posted the full news: "I've had the most brilliant, bewildering and life changing time working on Doctor Who. I have loved every day of it," the actor says. "It would be very easy to cling on to the TARDIS console forever and I fear that if I don't take a deep breath and make the decision to move on now, then I simply never will. ... I'm still the Doctor all next year but when the time finally comes I'll be honoured to hand on the best job in the world to the next lucky git - whoever that may be." Tennant added that he "always thought the time to leave would be in conjunction with Russell T Davies and Julie Gardner who have been such a huge part of it all for me. Steven Moffat is the most brilliant and exciting writer, the only possible successor to Russell and it was sorely tempting to be part of his amazing new plans for the show. I will be there, glued to my TV when his stories begin in 2010." He furthermore says that he feels "very privileged to have been part of this incredible phenomenon, and whilst I'm looking forward to new challenges I know I'll always be very proud to be the Tenth Doctor." Says Russell T Davies, "I've been lucky and honoured to work with David over the past few years - and it's not over yet, the Tenth Doctor still has five spectacular hours left! After which, I might drop an anvil on his head. Or maybe a piano. A radioactive piano. But we're planning the most enormous and spectacular ending, so keep watching!"

Says the BBC News site, Tennant is quoted as saying, "I love this part, and I love this show so much that if I don't take a deep breath and move on now I never will, and you'll be wheeling me out of the Tardis in my bath chair." Tennant also says, "I think it's better to go when there's a chance that people might miss you, rather than to hang around and outstay your welcome," he said.

Tennant will appear in this year's Christmas special, as well as four specials being produced for 2009 and 2010 airdates by executive producers Russell T Davies and Julie Gardner. Tennant confirmed to BBC News that the four specials for 2009/2010 will be "the four last stories that I do." New incoming executive producer Steven Moffat will then take over the series with new leads as the show returns for a normal, fifth series of episodes in 2010.

More details as they come in...

Russell T Davies and Benjamin Cook have given a wide-ranging interview to Simon Mayo of BBC Radio 5 Live, as part of the promotion for their book, "The Writer's Tale".
