0:00:02 > 0:00:07'The Doctor's time has run out, and now the ladies in his life need to turn back the clock.'
0:00:07 > 0:00:12- It's a Doctor-less world for her. - Donna displays great courage. - Activate!
0:00:12 > 0:00:17'So join Confidential backstage in a world bereft of the Doctor,
0:00:17 > 0:00:18'but blessed with a Noble and a Rose.'
0:00:40 > 0:00:43Filming the Shan Shen market was awful for weather.
0:00:43 > 0:00:45The rain, it was chucking it down.
0:00:45 > 0:00:49We brought all sorts of hocus-pocus-y sort of stuff,
0:00:49 > 0:00:52and brilliant banners, brilliant stalls, exotic fruits.
0:00:52 > 0:00:58We managed to find all Chinese extras from the west of England, so that was great.
0:00:58 > 0:01:04Everybody was very high-spirited, and thank God they were, because it could have been a thoroughly miserable day.
0:01:04 > 0:01:08And...action!
0:01:08 > 0:01:10HUBBUB OF VOICES
0:01:24 > 0:01:26'My entire contribution'
0:01:26 > 0:01:30to episode 11 was done in one day, which was a fairly manic day.
0:01:30 > 0:01:32We had Shan Shen Alley first thing.
0:01:32 > 0:01:36It was an extraordinary day, with this huge setup and all these supporting artists,
0:01:36 > 0:01:41all this set dressing, all this stuff, all these banners hanging from everything.
0:01:41 > 0:01:44Shan Shen Alley was a chance for the props department
0:01:44 > 0:01:47to use all the weird props they've never been able to use elsewhere.
0:01:47 > 0:01:52You could sell them on market stalls, in an alien marketplace. Perfect.
0:01:52 > 0:01:59So when you knew that you were bringing Billie back, Rose back, did you know that Bad Wolf would be...?
0:01:59 > 0:02:03I'd sort of thought... It's part and parcel of Rose, really, as a warning,
0:02:03 > 0:02:05as a message, a sign that goes with her.
0:02:05 > 0:02:09Rose was trapped in a parallel universe. The walls are closed.
0:02:09 > 0:02:14- Opening those walls was going to mean the deaths of all universes, everything collapses.- Yeah.
0:02:14 > 0:02:18If messages are bleeding through, if she's crossing universes, everything's in danger.
0:02:18 > 0:02:24- Not just this universe - everything. - But she's using Bad Wolf to let the Doctor know ahead of time.- Yes.
0:02:24 > 0:02:29- It's the bat signal, isn't it? - It is! That's a much better way of putting it.
0:02:29 > 0:02:31Take two.
0:02:31 > 0:02:33And, action!
0:02:35 > 0:02:40One of the things we address in the episode is, what the world would be like without the Doctor.
0:02:40 > 0:02:47What she doesn't know is that, in another life, another world, she was with the Doctor
0:02:47 > 0:02:49when he did defeat the Racnoss.
0:02:49 > 0:02:51Donna is connected to the Doctor.
0:02:51 > 0:02:54By her not meeting the Doctor in The Runaway Bride,
0:02:54 > 0:02:58the Doctor is killed. But the events of The Runaway Bride continue anyway.
0:02:58 > 0:03:03Some other secretary at HC Clements must have been dosed with Huon particles.
0:03:03 > 0:03:05The plan almost succeeded, the Doctor stopped them,
0:03:05 > 0:03:08but Donna wasn't there to stop him.
0:03:08 > 0:03:10Doctor!
0:03:10 > 0:03:12You can stop now.
0:03:12 > 0:03:15Loads of energy.
0:03:15 > 0:03:18What happened? What did they find?
0:03:18 > 0:03:21Did they find someone?
0:03:21 > 0:03:25I dunno. A bloke called the Doctor or something.
0:03:25 > 0:03:27< Cut there!
0:03:27 > 0:03:32Rose knows how important Donna is. Even though she sees herself as nothing, as she says.
0:03:32 > 0:03:35I'm nothing special! I'm a temp.
0:03:35 > 0:03:38Donna Noble, you're the most important woman in the whole of creation.
0:03:38 > 0:03:44Rose... Torchwood in Rose's universe is monitoring the timelines.
0:03:44 > 0:03:49'So, Rose has an overview, an objectivity of all that's going on.
0:03:49 > 0:03:53'Because their universe is slightly ahead of ours, she can see where'
0:03:53 > 0:03:58she needs to go in our universe to stop everything unravelling.
0:03:58 > 0:04:00Take two!
0:04:00 > 0:04:06- Wh... Where is he? - They took him away. He's dead.
0:04:09 > 0:04:12Sorry... Did you know him?
0:04:12 > 0:04:15Billie's return in Episode 11...
0:04:15 > 0:04:19We had to keep that under wraps. That had to be kept really quiet.
0:04:19 > 0:04:22'We never knew whether it would be two or three episodes.'
0:04:22 > 0:04:24I would've done with one scene in the end.
0:04:24 > 0:04:27'Planning for this goes back 18 months or so.'
0:04:27 > 0:04:30'When I found out I was returning to Doctor Who,'
0:04:30 > 0:04:34I was fine up until about three weeks before shooting.
0:04:34 > 0:04:36Then I had a minor breakdown.
0:04:36 > 0:04:38I thought I could never play that character again.
0:04:38 > 0:04:43'So, I went out, frantically buying boxsets'
0:04:43 > 0:04:45and watching my own performances!
0:04:45 > 0:04:47Such a sad confession!
0:04:47 > 0:04:51Episode 11's an extraordinary episode for Donna.
0:04:51 > 0:04:52Action.
0:04:56 > 0:04:59- This is where we leave you. - I don't want to see that thing on my back.
0:04:59 > 0:05:01'The moment in the circle of mirrors,
0:05:01 > 0:05:05'both times she's in the circle of mirrors. First of all, she's terrified.'
0:05:05 > 0:05:09And then she's so beautifully hopeful, travelling back in time.
0:05:09 > 0:05:13Those are some of the finest performances I've ever been associated with.
0:05:13 > 0:05:16At least I'm not gonna die!
0:05:16 > 0:05:18Cos I understand now.
0:05:18 > 0:05:23You said I was gonna die, but you mean this whole world.
0:05:23 > 0:05:26It's gonna blink out of existence. But that's not dying.
0:05:26 > 0:05:30Cos a better world takes its place. The Doctor's world.
0:05:30 > 0:05:32And I'm still alive.
0:05:32 > 0:05:34'And of course,'
0:05:34 > 0:05:36Rose knows differently.
0:05:36 > 0:05:37I'm sorry.
0:05:45 > 0:05:46I'm not gonna get there.
0:05:58 > 0:06:02She told me...to warn you.
0:06:02 > 0:06:04She said two words.
0:06:04 > 0:06:06What were they? What did she say?
0:06:12 > 0:06:13Bad wolf.
0:06:19 > 0:06:23Doctor, what is it? What's bad wolf?
0:06:24 > 0:06:27It's the end of the universe.
0:06:27 > 0:06:30We're heading to the series climax. All sorts of things are stewing.
0:06:30 > 0:06:35In every episode, there's elements being carried forward that will pay off in the finale.
0:06:35 > 0:06:37There's been the return of Rose.
0:06:37 > 0:06:40We've seen her now with Donna.
0:06:40 > 0:06:44We've seen Martha, before becoming part of the Doctor's world back on Earth.
0:06:44 > 0:06:47Those seeds and elements are all...
0:06:47 > 0:06:50It's like a rolling stone gathering moss.
0:06:50 > 0:06:53Something from every episode is about to pay off
0:06:53 > 0:06:57as we hit the biggest finale on Planet Earth!
0:06:57 > 0:06:59It's fantastic.
