The official Doctor Who website was today updated ahead of the broadcast of Cold Blood this weekend.

Included on its new episode guide are four preview clips and an introduction to the story from Meera Syal. There’s also a gallery featuring the episode stills we posted earlier this week. 

Airing this Saturday on BBC1/HD at 19:00, the story sees the Doctor face his toughest challenge yet.

In addition, LastBroadcast have posted their review of the episode, rating it 4 out of 5.

Chris Chibnall has promised that the conclusion to his Silurian two-parter will be “totally different” to part one.

He explained: “We always talked about that as a big split between the two episodes, that you’d start with quite a small canvas and then you would broaden. As the characters in the stories realise how much more there is, you’re going on that journey with them as a viewer. In part two you’ll see a lot of the Silurian city, you’ll see more Silurian characters, you’ll see more warriors. A lot takes place underground.”

The writer was speaking to SFX, also revealing there will be lots more Amy action in the episode, which airs this Saturday. “If anybody was going to be sucked under the Earth, it kind of had to be Amy,” he said. ”I do like it when the Doctor and the companion are split up. But you’ll see she’s very, very, very important in the second episode.”

In addition, the website has also released 11 teasers for the story.

The BBC have today issued nine new episode stills taken from this Saturday’s story, Cold Blood.

In part two of Chris Chibnall’s Silurian adventure, the Doctor faces his most difficult challenge yet, when he finds himself caught up in a battle in which he can’t take sides, as Earth face the dawn of a new age of harmony - or the start of its final war…

Cold Blood airs this Saturday at 19:00 on BBC1/HD.

The most ambitious drilling project in history has reached deeper beneath the Earth’s crust than man has ever gone before - but now the ground itself is fighting back. The Doctor, Amy and Rory arrive in a tiny mining village and find themselves plunged into a battle against a deadly danger from a bygone age.

So, there we have it – the end credits roll on another brand new adventure, which means it’s time to set your brains to ‘discuss’ and let us know what you thought of it!

In tonight’s long-awaited episode, penned by Chris Chibnall, we witnessed the return of the cold-blooded creatures known as the Silurians, who first appeared in the series in 1970. It was another blast from the past for the Doctor, but the resurrection of the reptile-like Earth-dwellers meant very bad news for the human race in the wake of history’s most ambitious drilling project, which ended up breaking more than just world records!

After the trials and tribulations faced by Amy and Rory last week, a nice break in Rio was just what the Doctor ordered, but unfortunately the TARDIS had other ideas, and our time travelling trio found themselves in a not-so-exotic mining village in the middle of Wales instead, where, naturally, there was great, great danger afoot. It wasn’t long before our heroes were thrown head first into battle with with an evil from a bygone age, and, this time, even the very ground beneath their feet can’t be trusted…

DigitalSpy have released a Q&A with Meera Syal, who appears as Dr. Nasreen Chaudry in the forthcoming two-parter, The Hungry Earth/Cold Blood. During the interview, the actress discusses the return of the Silurians.

“What’s great about them is that they’re not black and white baddies, they’re actually a highly intelligent and evolved race, who have technology way beyond the humans in many aspects,” she said. “However, they feel quite possessive about the Earth because they were there first.”

She continued: ”I think they’re scary enough for the little kids to get really scared, but then they’re also sort of interesting and multi-layered enough to just get to like them as characters, because they are distinctive characters. It’s not like the Cybermen, they are all really individual. And the humans behave pretty badly in this as well, so it’s a very equal argument, and there is a point where you think, this could go either way.”

The Hungry Earth airs this Saturday at 18:15 on BBC One and the BBC HD channel.

Meera Syal has spoken to SFX about her guest role in the Silurians two-parter, The Hungry Earth/The Cold Blood, which begins this week.

“My character’s a geologist, a very high-up, innovative geologist who is working for a company,” she revealed. “And her project is to drill as far as she can towards the centre of the Earth. And, in fact, the episode opens with her reaching the target, and she gets further than anybody else has ever done. And that’s what starts off the problems!”

Describing her character’s first encounter with the Doctor, the actress explained: “The Doctor happens to land where all this is going on, and there are really strange things happening in the village. And he traces all these weird happenings to what she’s doing. And then it all kicks off – that infrastructure starts collapsing, and she ends up going off with him, to find out what’s going on beneath the Earth.”

The BBC Press Office has today released the official synopsis for Series 5 Episode 9, Cold Blood.

It is the most important day in the history of Earth: the dawn of a new age of harmony or the start of its final war.

The Doctor must face his most difficult challenge yet. It is a battle in which he cannot take sides and a day when nobody must die…

The episode, part two of the Silurians adventure, is written by Chris Chibnall. It’ll air on BBC One/HD at the provisional time of 6:25PM on Saturday 29th May, with the slightly earlier starting time seemingly allowing the BBC to accomodate both Doctor Who and the Eurovision Song Contest (which takes place the same evening) this year. Geronimo!
