0:00:02 > 0:00:05Those big-headed Sontarans are still waging war.
0:00:05 > 0:00:06Change of plan!
0:00:06 > 0:00:10And they have an almighty chip on their shoulder.
0:00:10 > 0:00:12They look brilliant.
0:00:12 > 0:00:14A whole new dynamic of creature.
0:00:14 > 0:00:16We will ravage this planet!
0:00:18 > 0:00:21Because they have no fear of death, they are sort of unstoppable.
0:00:26 > 0:00:29They're truly brutal, nasty, monstrous creatures.
0:00:33 > 0:00:35# Tick, tick, tick, tick,
0:00:35 > 0:00:36# Tick, tick, tick
0:00:36 > 0:00:38# Boom. #
0:00:53 > 0:00:56It's battle stations for the Doctor Who production team
0:00:56 > 0:01:01as they plan, with military precision, the Sontarans' attack against UNIT forces.
0:01:05 > 0:01:06SCREAMING
0:01:09 > 0:01:13It's big battle time in this episode, and it's the first time ever
0:01:13 > 0:01:16on screen you get to see the Sontarans en masse.
0:01:27 > 0:01:30I just want to see hordes of them, armies of them,
0:01:30 > 0:01:32marching, guns, battleships, action,
0:01:32 > 0:01:36to see these soldiers, these famous soldiers of the Doctor Who universe,
0:01:36 > 0:01:39at war, in battle, fighting, and loving it.
0:01:42 > 0:01:44All troops. Code Red.
0:01:46 > 0:01:47This isn't war!
0:01:47 > 0:01:50Get them out of there. SONTARAN LAUGHS
0:01:50 > 0:01:51This is sport!
0:01:58 > 0:02:02They're running like slime bait from a spiel fox!
0:02:02 > 0:02:03Get them out of there!
0:02:09 > 0:02:11God save us.
0:02:16 > 0:02:18North America, online.
0:02:18 > 0:02:20United Kingdom, online.
0:02:21 > 0:02:23North Korea, online.
0:02:23 > 0:02:26The honour of battle.
0:02:26 > 0:02:27The glory!
0:02:29 > 0:02:32With the coordination of Tom, our stunt coordinator,
0:02:32 > 0:02:34and Ailsa, our choreographer,
0:02:34 > 0:02:38we really felt the full force of their warrior techniques.
0:02:40 > 0:02:45They're truly brutal, nasty, monstrous creatures, and that's what Sontarans are, they fight.
0:02:47 > 0:02:50At the moment we're waiting to go and shoot the big battle
0:02:50 > 0:02:53that we're going to be having with the UNIT troops.
0:02:53 > 0:02:55Action!
0:02:56 > 0:02:59And shooting various members of them.
0:02:59 > 0:03:02It's an interesting way to spend a morning, certainly.
0:03:04 > 0:03:09- Come on, come on.- What we're seeing on that is the soldiers running around, half panicking.
0:03:13 > 0:03:16Then the Sontarans come in into a set line,
0:03:16 > 0:03:18and then we had to work out different scenarios -
0:03:18 > 0:03:22running, falling and trying to shoot, but their guns are jammed.
0:03:22 > 0:03:25I think we really did get a sense of scale, in that we had
0:03:25 > 0:03:28these two big forces facing each other,
0:03:28 > 0:03:31and then throwing in our set piece special effects,
0:03:31 > 0:03:36in episode five, makes for a very dramatic sequence.
0:03:36 > 0:03:37Action!
0:03:38 > 0:03:40# You
0:03:42 > 0:03:43# Should
0:03:45 > 0:03:46# You
0:03:48 > 0:03:49# Live
0:03:49 > 0:03:53# The sun has gone and you're all alone
0:03:53 > 0:03:54# And you know
0:03:54 > 0:03:58# You're my dream. #
0:04:01 > 0:04:03We want to give them that testosterone.
0:04:03 > 0:04:07ALL: Sontar-ha! Sontar-ha! Sontar-ha!
0:04:07 > 0:04:08ALL: Sontar-ha!
0:04:08 > 0:04:14They just needed that release, that joy in battle, beyond just saying, "I'm having fun."
0:04:14 > 0:04:20I thought that chant brought out their aggression and their rituals and also their fun,
0:04:20 > 0:04:24but also the fact that they're all of one like mind, they are clones.
0:04:24 > 0:04:28They do things together. They all join in exactly the same actions and words.
0:04:28 > 0:04:30It just seems really Sontaran to do that.
0:04:30 > 0:04:34About three or four weeks ago when the guys first came together,
0:04:34 > 0:04:37we did a few basic exercises
0:04:37 > 0:04:40just running things, just some marching,
0:04:40 > 0:04:45to get everybody in the feel of the quality of movement that we were actually looking for.
0:04:45 > 0:04:47D camera.
0:04:48 > 0:04:49OK, and...
0:04:49 > 0:04:52Three, two, one, action!
0:04:52 > 0:04:55400 million weapons!
0:04:55 > 0:04:56Sontar-ha!
0:04:56 > 0:04:58Sontar-ha!
0:04:58 > 0:05:01I seem to remember saying that quite a few times.
0:05:01 > 0:05:04ALL: Sontar-ha! Sontar-ha! Sontar-ha!
0:05:04 > 0:05:06ALL: Sontar-ha!
0:05:06 > 0:05:09My left palm was very sore
0:05:09 > 0:05:12at the end of...after each session of my Sontar-ha-ing.
0:05:12 > 0:05:16ALL: Sontar-ha! Sontar-ha! Sontar-ha!
0:05:16 > 0:05:17ALL: Sontar-ha!
0:05:17 > 0:05:18Gimme a break.
0:05:19 > 0:05:22It's a good chance... When we come back to Earth, mid-series,
0:05:22 > 0:05:25it's a good chance for the companion to develop.
0:05:25 > 0:05:27For example, Donna gets her key to the Tardis.
0:05:27 > 0:05:30Oh, I've never given you a key!
0:05:30 > 0:05:32Keep that. That's yours. Quite a big moment.
0:05:32 > 0:05:35She's given a key to the Tardis, yeah,
0:05:35 > 0:05:39which, in true Donna fashion she goes, "Never mind. Don't get all sentimental,
0:05:39 > 0:05:41"cos I'm choking to death."
0:05:41 > 0:05:43Action!
0:05:49 > 0:05:52Look after yourself. Get yourself in the building.
0:05:52 > 0:05:55What's perhaps different to the Doctor and Donna's relationship
0:05:55 > 0:05:58to relationships that we've seen the Doctor have before
0:05:58 > 0:06:02is that Donna herself feels no need to prove herself.
0:06:02 > 0:06:03SHE COUGHS
0:06:03 > 0:06:08- God, this air's disgusting! - It looks bad. Get in the Tardis.
0:06:08 > 0:06:12Oh! I've never given you a key!
0:06:12 > 0:06:14She's very much her own woman
0:06:14 > 0:06:20and I think the Doctor therefore goes along with that.
0:06:20 > 0:06:23'Keep that. That's yours.'
0:06:23 > 0:06:24Quite a big moment, really.
0:06:24 > 0:06:29- Yeah. Maybe we'll get sentimental after the world's finished choking to death.- Yeah, good idea.
0:06:29 > 0:06:34Donna's not been waiting, going "Oh, you know. Are you going to tell me the alarm code?"
0:06:34 > 0:06:38I don't think she's really reading into that in any way.
0:06:38 > 0:06:40Donna just forces herself upon him
0:06:40 > 0:06:43and inhabits the Doctor's life from the moment she steps on board.
0:06:43 > 0:06:46I can't believe I'm doing this!
0:06:46 > 0:06:47No, neither can I.
0:06:47 > 0:06:50For instance, when the Doctor gives her a Tardis key,
0:06:50 > 0:06:52I think he assumed he'd already done it.
0:06:52 > 0:06:56She treats it in a much more cavalier way than either Rose or Martha did.
0:06:56 > 0:06:58None of that. The world's choking to death.
0:06:58 > 0:07:03With Rose and possibly even more with Martha there was a sense that perhaps they felt
0:07:03 > 0:07:06they didn't quite deserve to be there.
0:07:06 > 0:07:08What's happened? Where are you?
0:07:08 > 0:07:11Still on Earth. But don't worry. I've got my secret weapon.
0:07:11 > 0:07:15- 'What's that?'- You! - Somehow that's not making me happy!
0:07:15 > 0:07:19Companion alone on an alien spaceship and all she's got is a hammer.
0:07:19 > 0:07:23It's like there's something really dreadful about that,
0:07:23 > 0:07:28genuinely full of dread, in that the Doctor isn't there, and he isn't there to save her.
0:07:28 > 0:07:30It's a scary place to be. It's very alone.
0:07:30 > 0:07:35I find that very, very scary. It's one of my favourite sequences, because of the loneliness of it.
0:07:41 > 0:07:46- There's a Sontoran... Sont-A-ran. - Did he see you?- No. He's got his back to me.
0:07:46 > 0:07:48'Listen, on the back of his neck,'
0:07:48 > 0:07:52on his collar, there's a plug, a hole, the probic vent. 'One blow to the probic vent
0:07:52 > 0:07:59- 'knocks him out.'- But he's going to kill me.- I'm sorry, I swear, I'm so sorry, but you've got to try.
0:07:59 > 0:08:01She does have a wobble. And that's quite unusual.
0:08:01 > 0:08:06Because we haven't really seen that from her, because she is quite sure of who she is,
0:08:06 > 0:08:08of what she can do and what she can't do.
0:08:08 > 0:08:13- But I can't even mend a fuse! - Donna! Stop talking like that. You can do this. I promise.
0:08:13 > 0:08:17When the Doctor really has to push her, it feels...
0:08:17 > 0:08:19new and he's sorry for it.
0:08:19 > 0:08:20But what if they find me?
0:08:21 > 0:08:24I know. I wouldn't ask, but there's nothing else I can do.
0:08:24 > 0:08:26The planet's choking, Donna.
0:08:26 > 0:08:29The Doctor almost regrets having to push her into situations
0:08:29 > 0:08:32where she wouldn't feel entirely comfortable.
0:08:32 > 0:08:36But of course he does, because he has to and of course she fulfils it, because she is
0:08:36 > 0:08:39perhaps more able than she believes herself to be.
0:08:39 > 0:08:42She rises to the occasion. She does.
0:08:42 > 0:08:48And I think she sort of finds this strength within her, and I don't know if she knew she had it.
0:08:48 > 0:08:52Because she's cocky and she's mouthy and she's ballsy,
0:08:52 > 0:08:57but that doesn't necessarily mean she's brave in the face of alien warfare!
0:08:59 > 0:09:01But it turns out she is!
0:09:01 > 0:09:03There's something very human about that.
0:09:03 > 0:09:07She doesn't suddenly become some superhero and step up to the mark
0:09:07 > 0:09:09in a way that's just too much.
0:09:09 > 0:09:10And action!
0:09:25 > 0:09:26Back of the neck!
0:09:26 > 0:09:31Here's a bit of trivia for you. It was supposed to be a shoe.
0:09:31 > 0:09:35But because I only wear trainers, they didn't want it to be a trainer,
0:09:35 > 0:09:39or thought probably a trainer would just bounce off the back of his neck,
0:09:39 > 0:09:41so I had to have a mallet.
0:09:46 > 0:09:49- I'm through. - Oh, you are brilliant, you are!
0:09:49 > 0:09:51DOOR CLUNKS
0:09:51 > 0:09:53Shut up!
0:09:53 > 0:09:58Previously he's been more used to being admired and slightly goggled at.
0:09:58 > 0:10:01With various parts of the story, Donna becomes more of the companion.
0:10:01 > 0:10:04There's some really brilliant stuff to come.
0:10:04 > 0:10:09It's part of the new...the different flavour that Donna brings.
0:10:10 > 0:10:11Hello.
0:10:14 > 0:10:16Doctor!
0:10:16 > 0:10:19# I walked out cos I had some plans
0:10:19 > 0:10:21# Yeah, I walked out
0:10:21 > 0:10:24# Destiny in my own hands
0:10:24 > 0:10:28# I thought I'd get by without you
0:10:28 > 0:10:31# Thought I'd survive without you... #
0:10:31 > 0:10:33Donna Noble, since you didn't ask.
0:10:33 > 0:10:35I'll have a salute.
0:10:36 > 0:10:38- Ma'am!- Thank you.
0:10:39 > 0:10:44# Cos I can't get along without you
0:10:44 > 0:10:47# I can't get along without you
0:10:47 > 0:10:52# I can't get along without you
0:10:52 > 0:10:53# No, something is wrong
0:10:53 > 0:10:58# I can't get along without you... #
0:10:58 > 0:11:00Come on.
0:11:00 > 0:11:03# So I picked fights with men twice my size... #
0:11:04 > 0:11:07- And you're would be? - The Doctor and Donna Noble.
0:11:07 > 0:11:11Representing the Noble Corporation Plc Ltd, intergalactic.
0:11:13 > 0:11:16- It's always like this with you, innit?- Oh yes, and off we go!
0:11:16 > 0:11:20# Can't get along without you
0:11:20 > 0:11:24# I can't get along without you
0:11:24 > 0:11:30# I can't get along without you, girl
0:11:30 > 0:11:32# Believe me, baby
0:11:32 > 0:11:37- # Can't get along without you - Can't get along
0:11:37 > 0:11:41- # I can't get along without you - Can't get along
0:11:41 > 0:11:45# I can't get along without you
