The MediaGuardian website has published an article by Stephen Brook previewing some of the work effects house The Mill has performed for the first episode of the new series of Doctor Who. The article looks at how the Adipose were created for the episode, including images.

Stephen Regelous, who worked on the episode, is quoted as saying that: "When I first found out that the Mill was working on Doctor Who, I was quietly hoping that Massive might be used to create hordes of Daleks or Cybermen and with series 4, I jumped at the opportunity to be involved. It's been very fulfilling to be a fan from about three or four years old and finally be able to contribute to the Doctor Who universe."

There is some spoiler content, so those not wishing to learn anything about the episode until its transmission should not read the piece.

David Tennant was interviewed by Simon Mayo on BBC Radio Five on Wednesday. APodcast of the interview is available for the next seven days.

A reminder that David Tennant and Catherine Tate will be guests on Friday nights Jonathan Ross show on BBC1.

In this week's Radio Times, Russell T Davies talks about how he goes about casting Doctor Who. "You can't really write with a guest star in mind - well, only in very exceptional cases. Kylie Minogue was one. There's a great danger in writing for someone and then they get offered a film, or they just don't fancy it. So it's dangerous territory to enter."

One of the things I love about this job is working with actors. It's such a strange process where you hand the script over to a bunch of complete strangers, but you have to trust them, and when you cast it well, that trust is paid back. Undoubtedly, they have fun doing it, but not so much fun that it looks like fun on screen." Every guest actor says, "My children would have killed me if I hadn't taken the part." Even those who haven't got children have nephews and nieces. Not just some of them say it – every single one of them does. It's a litany as they arrive. And it's absolutely true!"

Catherine Tate tells of her reaction when asked to reprise the role of Donna Noble, "I couldn’t have been more surprised. I went out to lunch with [executive producer] Julie Gardner and I thought we were just there to chat. When people say, “My jaw hit the floor". I know what they mean!". David Tennant talks about the Doctor's reaction to the reunion. "He’s pretty gobsmacked. Donna’s quite a force of nature, she doesn’t really take no for an answer."

The Magazine also contains an article on first producer Verity Lambert, and looks ahead to the tribute on BBC Fourthis weekend. It was to Lambert’s 60s version that Davies turned for inspiration when kick-starting new Doctor Who in 2005, because, "It was before the series became bogged down in any continuity. There was just mystery. An open road – that’s what she created."

BBC News Online features an article on the press launch of Series 4. The executive producer Russell T Davies tells how he wants David Tennant to stay on forever. When quizzed about his own future with the programme, Davies told reporters it was "none of their business. Never mind what happens behind the scenes," he said "it's what happens on Saturday night that's important." The website includes video interviews with Tennant and Tate and clips from the new series.

The launch is also featured in a number of national newspapers. The Telegraph reviews the first episode and asks Who is the best Who? The Mirror andThe Sun also review the first episode.

The start time of Series Four of Doctor Who is likely to return to 7.00pm around Episode Five or Six according to the BBC's internal magazine Ariel.

The show's Executive Producer, Russell T. Davies, interviewed at the Series Four Press launch, admitted he would have preferred a later time slot, but was diplomatic about the scheduling decision which he said last week could lose the show a million viewers.

"It's not a time slot I agree with, but I know that no one wants to damage the brand", he said calmly. "In the past we’ve got higher figures when it went later, but it will shift later on in the run, around episode five or six, which the BBC was going to do anyway."

Also at the launch Ariel spoke to Jane Tranter, BBC controller BBC Fiction who thanked the "loyal, professional and all round excellent team" in Cardiff, most of whom have worked on all 56 episodes. "The success of Doctor Who is to a great extent theirs," she said. Tranter described new companionCatherine Tate as "the most empathetic, big hearted and extraordinary of the Doctor's companions", praising her "versatility, bravura and humanity as an actress".

Meanwhile David Tennant promised the series four finale would be the "biggest, boldest, maddest, saddest, most exciting story we've ever done".

This week's TV Times features an article on the return of Doctor Who. The magazine is running a competition to win a bronze Dalek, to tie in with the start of Series Four.
