David Tennant praises newcomer Freema Agyeman in an interview today on Sci Fi Wire.

In the interview, conducted by e-mail, he tells the Sci Fi Channel's news service that the actress "hit the ground running" when she took on the role of Martha Jones, and said he let her deal with the pressure of replacing such a popular and high-profile cast member as Billie Piper in her own way.

Tennant says Agyeman "inhabited Martha Jones from day one without a hint of trepidation or nervousness. I found myself quite envious of her confidence. She is going to be brilliant."

He also tells of how difficult it was to shoot the final scenes with Piper, saying they started sniffling during a run-through of the lines on the make-up bus.

Tennant says Martha and the Doctor have an entirely different relationship to Rose and the Doctor, adding: "As with any big relationship, it takes time for the scars to heal. Perhaps the Doctor feels like he's dealt with it, but Martha might disagree." He also says she "makes herself indispensable".

ITV broadcast the first part of their new series, Raiders of the Lost Archive, last night; presented by Paddy McGuinness, the show features clips for famous television personalities that were thought to be lost to the archives.

The programme has been made through searches through industry archives and private collections, and the show has also made an appeal for other shows to be returned, in a similar vein to the BBC's own Treasure Huntappeal. This new more general initiative has its own website to accompany the show, and includes a section for the 50 most wanted television shows - of which Doctor Who is listed (number 12 in the alphabetical list). Says the site: "Over 100 episodes of this ever popular series are missing or part missing – all from the black and white 60s era of the show. Doctor Who fans are particularly interested in recovering “The Tenth Planet” Episode 4 which was first broadcast on October 29, 1966. It was the final story of the first Doctor, William Hartnell’s era and the first story to feature the Cybermen. Patrick Troughton also makes his first, uncredited appearance as the Second Doctor. Many classic gems now survive only as soundtracks and photographs. Additionally, some Jon Pertwee 70s episodes made in colour only survive in b/w. Do you have “The Web of Fear” episodes 2-6 or “Fury from the Deep”?"

The next show will feature a very young David Tennant (above) in an early television appearance!

A reminder to Outpost Gallifrey readers that David Tennant is the guest presenter tonight on The Friday Night Project on Channel 4.

During the programme, he will give a monologue and face a grilling from the studio audience.

The entertainment show - returning for a fourth series - is on from 11.05pm to 12.10am.

There is also mention of this on Yahoo Entertainment News (with a picture of a blonde-wigged Tennant) and on Digital Spy.

A Fan Website dedicated to David Tennant has announced that he is "committed to the series" despite rumors in the tabloids that he was going to quit after the third series.

The article says, "David is absolutely committed to the show and is currently filming the third series. There is no fourth series currently commissioned yet so we could not confirm his involvement in that yet. When a further series is commissioned, we will be able to confirm his involvement."

The website also lists the fact that there will be another Christmas Special in 2007. However, this news cannot be confirmed at this stage.

If proof were needed, David Tennant has had his A-list celebrity status confirmed by being included in the UK's annual publication of Who's Who 2007, which is a directory of society's rich, famous and influential. The reference work has been published since 1849 and has become a benchmark of the genuinely famous in public life.

Tennant, one of the 1000 new entries, was by tradition invited to submit his potted biography. New entries are given free rein to write their submission, but Tennant restricted himself to basic details, which are descibed by Wednesday's Scotsman as "tantalisingly brief. He mentions his father, the Very Rev Alexander McDonald, but not his mother. He gives no details about his love life and does not list any recreations." He lists himself under his real name, David John McDonald, 35-year-old from Renfrewshire.

Other new entries include presenter Noel Edmonds, veteran actor Denis Lawson (listed as Ewan McGregor's uncle), Dame Maggie Smith's actor son Toby Stephens, comedy actor and writer Sanjeev Bhaskar, author Kate Mosse, and the designer of the iPod Jonathan Ive.

The book is published on Wednesday 3rd January, at the noteworthy price of 145 pound sterling. It is not known if those listed receive a complimentary copy. Further details can be found here.

This story of Who appearing in Who's Who is also in the Daily Record, The Guardian, the Metro, The Sun, andThe Telegraph.

The BBC have issued a statement reported by the Press Association to refute any decisions made by cast or crew over the fourth series of Doctor Who.

Reported by BBC News, CBBC, icWales, Press Association, 24dash, Manchester Evening News.

The Thursday issue of the Sun is reporting that David Tennant is to quit the title role of Doctor Who midway through the fourth series. The story is headlined on the front page (see right) with the article on page five (see quote box below).

It is worth stressing that, so far, this story is unconfirmed, and Tennant and the production team are still working on the forthcoming third series. A fourth series is yet to be officially commissioned by the BBC, but assuming it goes ahead, it wouldn't be due to hit our screens until Spring 2008 and would mark Tennant's third season in the role. Tennant's first complete story was in the Christmas special 2005.

Update: In an unhelpful move, BBC Radio One have managed to mis-report the story in the Sun this morning, with news summaries during their breakfast programme quoting a newspaper as saying that Tennant will leave "during the next series". Naturally, many listeners may assume this is referring to the forthcoming third series yet to begin broadcasting. However, this is still quoting the tabloid, even if it is a mis-quote, and does not validate the story. The Metro is also quoting The Sun's report, offering no additional information.

(Humorous footnote: There may not be any official confirmation or denial about the story as yet, but there is a "News In Briefs" comment by Thursday's page three model - Katie, 22, from Liverpool - who is reported to be "gutted" that Tennant was supposed to be leaving. She is quoted as saying: "He was brilliant in the show and it won't be the same without him. Not only was he a great actor - but I could swoon over him as well!" Additional reporting by John Bowman)

Below are several screen grabs from David Tennant's appearance last night on Friday Night with Jonathan Ross, including a Dalek toy introducing Tennant to Ross and the audience, the singers with Tennant's face on their shirts, and even a new 'action figure' of the tenth Doctor! Click on each for a larger version. Tennant appeared on the talk show to promote tomorrow night's airing of "The Christmas Invasion" and his debut as the Doctor.

David Tennant's appearance as guest presenter on Channel 4 entertainment show The Friday Night Project, reported at the beginning of this month on Outpost Gallifrey, is scheduled to be broadcast on January 5 at 11.05pm.

As the celebrity guest in the first edition of the fourth series, alongside comedians Justin Lee Collins and Alan Carr, he will be providing an opening monologue, as well as performing comedy sketches and participating in games.

It is not known if there will be a question-and-answer session with the audience, as there was last January when Billie Piper was a guest host.
