Executive Producer and Head Writer Russell T. Davies reveals that the forthcoming Doctor Who special Planet Of The Dead will serve as an "antidote" to recent adventures.

The departing showrunner told Doctor Who Magazine: "After the events of Journey's End and The Next Doctor I think it's time to get away from the past and have an adventure with lots of new elements. And lots of fun too!

"The next Special should be a nice antidote to Christmas, with a bit of sunshine if we're lucky. And with not one but two alien races that you've never seen before."

The New Year's Day repeat of The Next Doctor was watched by 2.2 million viewers according to unofficial overnight figures. The programme, shown at 2.45pm, had a 15% share of the total television audience and was just out-rated by Agatha Christie's Poirot on ITV1 which had 2.4 million watching. Overall, Doctor Who was the 21st most-watched programme of the day. The Doctor Who Prom was watched by 1.7 million, with a 12.6 % share of the audience.

The Next Doctor had an Appreciation Index figure of 86 making it the second most enjoyed programme on mainstream television on Christmas Day. The only programme to score higher was Wallace and Gromit: A Matter of Loaf and Death which scored 88.

The Appreciation Index, or AI, is a measure of how much the audience liked the programme. It is a score out of 100, based on responses from a carefully selected panel. The average score for drama on BBC1 and ITV1 is 77. A score in excess of 85 is regarded as excellent while a score below 60 is poor.

With overnight figures now available for the whole of Christmas week, Doctor Who stands as the second most watched programme of the week, a position it is expected to retain when BARB releases the corrected figures next week. If so this would be the fifth top five place in succession, a record for the programme.

Following the broadcast of last night's Christmas special episode of Doctor Who, "The Next Doctor", on BBC One, various newspapers and websites have been publishing their reactions both to the episode itself and its high position in the Christmas viewing charts.

The Telegraph's Christmas television review praises the episode, claiming that "As Morrissey's Doctor said, it was complete and utter nonsense, but wonderful nonsense, nevertheless." In The Mirror, critic Jim Shelley wrote that BBC One's Christmas schedule as a whole "From 2pm through to 11.35pm... was perfect viewing." He wrote of "The Next Doctor" that: "David Morrissey threw himself into the part and showed that if he gets the call he has the gusto to make a classic old-fashioned Doctor Who... Up against all this, the other channels simply rolled over." TV Scoop, meanwhile, was less impressed, calling the episode "something of a swing and a miss."

The high viewing figures attained by the episode have been covered across a wide variety of media. BBC News, along with several other outlets, has ranked the Christmas Day programmes in order of peak rather than average viewing figures, placing Doctor Who third rather than second. The main thrust of most media reports of the Christmas ratings, nonetheless, is BBC One's resounding victory over their main rival, ITV1. This is the angle taken by the Daily Mail. Other outlets covering the ratings results include The Guardian, The Sun, TeleText, CBBC and Digital Spy.

Unofficial overnight figures show The Next Doctor was watched by 11.7 million viewers, a share of 50.5 per cent of the audience.

The rating is the highest achieved by the programme in 2008 and the second highest since the programme returned in 2005, only being beaten by last year's Christmas special.

The programme was the second-highest rated of Christmas Day and of Christmas week so far, beating EastEnders, even though the soap was shown in a much later slot. The highest-rated programme of the day was Wallace and Gromit: A Matter of Loaf and Death with a massive 14.3 million watching.

BBC One ruled the day with the top seven places. The highest rating ITV1 could achieve was an average of 7.4 million for Coronation Street. Against the Doctor, Emmerdale could only manage 4.8 million viewers.

Doctor Who is now the tenth-most-watched programme of 2008, although this position could rise when final figures, including for those who recorded the programme and watched it later, are released by BARB in about two weeks' time.

On BBC3 Doctor Who Confidential had an audience of 0.46 million and Doctor Who: Top 5 Christmas Moments was watched by 0.48 million viewers. Gavin and Stacey: 12 Days of Christmas was the highest- rated programme on multi-channel television.

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.

BBC One magazine programme The One Show has put online its behind-the-scenes look at The Next Doctor from last Friday.

The four-and-a-half-minute video exclusive is presented by famed Tom Baker impersonator Jon Culshaw, who goes on set and interviews David Tennant and David Morrissey.

The official BBC Doctor Who website has posted a clip from the forthcoming Christmas special, "The Next Doctor", as the treat behind the door of day 21 on their "Adventure Calendar". The calendar counts down to Christmas with a variety of special material made available each day in December.

The new 50-second video clip, only available to UK users of the site, features the character of Miss Hartigan (Dervla Kirwan) interacting with the Cybermen.

The Next Doctor will make its Australian debut on the Australian Broadcasting Corporation on Sunday 25 January 2009 at 7.30pm on ABC1. This contrasts with previous years when the Christmas specials have debuted on ABC TV several months after the UK. This may also suggest that the ABC will 'fast-track' the other Doctor Who specials to be broadcast in the UK in 2009.

The ABC has also confirmed the Australian broadcast details of the 2008 Christmas special on its website.
