Various members of the Doctor Who cast have been out and about promoting the forthcoming series-ending two-parter on British television this week. Things began on Tuesday, when Freema Agyeman appeared as an in-studio guest on children's show Blue Peter (see picture), talking about the programme and helping show viewers how to make their own Doctor Who board game. The episode also featured a report on Blue Peter presenter Gethin Jones's turn as a Dalek in the forthcoming series finale, including a never-before-seen clip from episode thirteen. British broadband viewers can watch this edition of Blue Peter online on the BBC iPlayer.

On Thursday Bernard Cribbins, who plays Donna's grandfather Wilf, appeared on BBC One's early evening magazine programme The One Show, and an exclusive clip from the series was shown. Cribbins commented that he was interviewed for the role of the Fourth Doctor, but lost out to Tom Baker. The One Show is also available to view on the BBC iPlayer for British internet users.

On Friday morning, Freema Agyeman and Elisabeth Sladen appeared together on Richard Arnold's entertainment news show, part of the morning GMTV programming on ITV1. They discussed the forthcoming finale and verbally sparred with a Dalek who also featured in the studio!

On Friday afternoon, British-based American actor Michael Brandon appeared on husband-and-wife team Richard and Judy's chat show on Channel 4. Brandon enthused about his role in the forthcoming episodes, and another exclusive clip was shown.

A blog on the website of the American Wall Street Journal newspaper looks into why British fans are so excited about the forthcoming finale - spoilers are included, so be warned. The Toronto Star in Canada includes K9 in a run-down of famous "cute" science-fiction robots. The Scotsman, meanwhile, reports that BBC bosses are allegedly ready to offerDavid Tennant 100,000 pounds per episode to sign up for the fifth full series of Doctor Who.

The Stage entertainment industry newspaper previews tonight's episode in its Square Eyes column, saying that: "The Stolen Earth is an audacious yarn from the pen of Russell T Davies - it's like one of those cracking Marvel Comic team-ups that have Spider-Man, the X-Men and The Avengers all turning up in the same comic." The Scotsman also runs a preview, enthusing: "This crowd-pleasing episode is so relentlessly enjoyable I wouldn't be ashamed to run naked around Westminster Abbey roaring its praises to the rafters. Look for me on the news."

The current edition of the BBC's Radio Times listings magazine also praises the episode, making it their "Pick of the Day" for Saturday, with television editor Alison Graham commenting: "Even sensible adults in the audience might feel a tiny quiver of fear as the Daleks deliver their message to Earth in those unforgettable quivering voices: 'Exterminate! Exterminate!'." The magazine also has a brief interview with scientist Richard Dawkins about his cameo appearance in the programme, and a three-page feature on the return of the Daleks.

Website Den of Geek has interviewed Dalek voice artist Nick Briggs about various aspects of his Doctor Who career.

The BBC has started running two new trailers for episode 12 of the current series, separate from the "Next Time" trailer seen last night. There is a 10-second teaser trail featuring the Daleks, and a longer 30-second trail containing many elements from the episode, including a malevolent voiceover.

UK internet users can view both of the trailers on the official BBC website, or on the BBC YouTube channel.

The Radio Times is not the only British listings magazine to devote its cover to the return of Rose Tyler this week - both TV and Satellite Weekand TV Guide also make the news their cover story, with corresponding articles inside.

In the TV Guide feature, Russell T Daviessays of Rose's return: "She's a huge protagonist in the action and we see her meeting Donna for the first time. It explores how the two of them get on and, of course, they both have different agendas." In TV and Satellite Week, Davies comments on his successor,Steven Moffat: "It will be brilliant to watch it as [he] is full of ideas. You have never seen a man more excited than Steven is."

The Sun newspaper has today published a short article with a screen grab from this Saturday's episode - it is a minor spoiler, so be advised. Meanwhile,The Stage has published its review of last weekend's episode, "Midnight", saying it is Russell T Davies's "finest script from four years of Doctor Who".

SFX Magazine has gone a week further ahead and posted a preview of episode 12, "The Stolen Earth", which can be found here. Again, minor spoilers are included, so watch out if you are avoiding all advance details about the episode.

Meanwhile, an actor appeared on the BBC's "Breakfast" news programme earlier this week, and confirmed that he will be appearing in a forthcoming episode of Doctor Who. No plot spoilers were given, but for the benefit of those avoiding casting details, the information is included in the spoiler box below.

The Sun daily national newspaper in Britain has published a story about a returning enemy in the final two episodes of the current series of Doctor Who. The story also features a high-quality photograph of this character, and also of another aspect due to feature in the finale. The information is contained in the spoiler box below - please do not click if you do not want to be spoiled!

Today's Daily Telegraph is also running the spoiler story, although their photograph is not from the current series.

The returning enemy is Davros, the creator of the Daleks, previously seen in five classic series stories. According to both papers, he is now played by actor Julian Bleach, who previously appeared in an episode of Torchwood.

A new type of Dalek, a Red Dalek, is also pictured in The Sun's story.

The most recent episode of Doctor Who, "Midnight", is reviewed in two of the British broadsheet newspapers this morning. The Times's reviewer Andrew Billen felt that the episode was "too much of a writing exercise to be really scary," however he does concede that: "It showed that even if it fails as often as it succeeds, this series is not afraid of variety. Like the passengers aboard the charabanc, Doctor Who is dead scared of repetition." Sam Wollaston of The Guardian gives a very positive assessment: "It's great. Because what we can't see is much more alarming than what we can. It's tense and claustrophobic, and it gnaws away at you."

icWales yesterday published an article examining what next for Welsh-produced drama once Russell T Davies leaves Doctor Who, claiming that Welsh drama productions are the envy of Scotland's First Minister Alex Salmond. The article rather oddly refers to Davies's successor, Steven Moffat, as first English, before later pointing out his Scottish origins.

Davies's impact on television drama is also examined further afield: the New York Times and the International Herald Tribune have both published a piece by journalist Sarah Lyall, looking at Davies and Doctor Who's influence on the industry and British popular culture as a whole.

It's not uncommon for British political cartoonists to cast politicians as Daleks or Cybermen, but it's far more rare for Doctor Who to be referenced in American media.

However, this week liberal American cartoonist Tom Tomorrow included the Tenth Doctor and the TARDIS in his weekly cartoon This Modern World, by way of making a comment about Barack Obama winning the Democratic Party's presidential nomination.

The panel can be seen at right, and the full cartoon can be read at Salon.com.

David Tennant was a special guest on the BBC1 Sunday morning programme The Andrew Marr Show.

Sandwiched between the Mayor of London and the Home Secretary, and appearing primarily to promote the DVD release of the BAFTA winning Taking over the Asylum and his forthcoming appearance as Hamlet, Tennant also talked about his role as the Doctor.

Asked whether he would be appearing in the fifth series, Tennant said he hadn't yet been asked, but would consider the question if it came. He confirmed he will be appearing in four specials to be shown in 2009.

The interview can be viewed here and a transcript can be read here. The whole programme can be watched on theBBC iPlayer.

David Tennant also joined current show-runner Russell T Davies and show-runner elect Steven Moffat in this week's Doctor Who Podcast. As well as providing a commentary to Moffat's Forest of the Dead, the trio discussed Moffat's appointment as the head of the series as well as their favourite Borusa and their thoughts on The Keys of Marinus.

Steven Moffat has given his first full-length interview since being announced as the next lead writer and executive producer of Doctor Who to the new issue of Big Issue Scotland, the weekly magazine sold by the homeless in Scotland.

In the interview, Moffat admits that he had to think hard about whether to accept the role, comparing his replacing Russell T Davies with fellow Scot Gordon Brown succeeding Tony Blair as Prime Minister.

"You wouldn’t immediately say yes to that job. You imagine that you would say yes immediately, but it’s a huge job and you have to think about it," he tells the magazine. "I was kind of the other contender, which puts me sort of in the position of Gordon Brown. And look how that turned out. The surly Scot comes in and it all goes to ******."

The full interview is available in Big Issue Scotland, on sale now across Scotland.

The news that Steven Moffat is to replace Russell T Davies as the lead writer and executive producer of Doctor Who has garnered a large amount of media reaction, particularly in the UK. On Tuesday after the news broke the story was even featured on the BBC News television channel, as well as in the hourly bulletin on BBC Radio 2, the most listened to radio station in Britain. The BBC News website also ran an article, which was the main front page feature in their Entertainment section after the news broke on Tuesday.

The story ran in British national daily newspapers, such as The Mirror and The Times, and today The Independentpublished an opinion piece by Thomas Sutcliffe, bemoaning the fact that Moffat's talents were, like Davies's, to be wasted on a children's programme such as Doctor Who. Industry newspapers such as The Stage, Broadcast and even the Hollywood Reporter in the United States ran articles on the news.

Reaction has not been limited to news sources - blogs have been particularly active in relaying and commenting upon the news. Doctor Who scriptwriter Paul Cornell, celebrated comics writer and novelist Neil Gaiman, writer Warren Ellisand musical comedian Mitch Benn are all amongst the many hundreds to have passed comment on the news in their online journals.
