What is it with you know, the doctors and scared everyone scared Dr Yang as Graham Ryan roll back in Sheffield catching up with their families and friends.

They're about to go off travelling again when they are essentially kidnapped.

End up in this call and driven by a on agent special agent to take us to where my six was back to normal because you're in a wet situation with the gang again.

My idea is that we just let the driver take us to where he wants us to go to.

Some will find out who wants us or if he kills us along the way.

Okay.

Doing this, someone else's orders that you want to know.

That is, all of a sudden the m I six agent gets killed whilst we're driving along at speak.

Your equipment's know too much.

Shouldn't be doing that on then.

This entity, whatever it is, takes over the car.

We are at the hands of an invisible force that is reversing down a motorway so much controlling this governor isn't made tonight.

We're filming all of the exterior stuff with the stunt cars on then at a later date will pick up all the stuff inside the car in a studio with our cast.

It's probably one of the biggest stunt sequences that the show's ever undertaken when any car sequence I always like to use my toy cars.

So I used my two boys.

I get to go to their cover and I get that toy cars out.

He's gonna go between Lloyd Joel.

It's just a visual aid that everyone can see exactly what you're doing.

So I lay them out on the road, on the ground as it's going to be on the day, and then everyone knows what they're doing.

Where the camera's gonna be makes life a lot easier, and it helps me enormously for rehearsals.

It is a big number.

We've had to close off the road that I've got 11 stunt drivers, got a hero car that's driving at speed.

It needs to weave in and out of the traffic, comes to a very, very sharp stuff, and then the car gets possessed, and then it stops to reverse at high speed through all the oncoming traffic through the tunnel, reversing into oncoming cars sounds straightforward enough, but when you add darkness, headlights, possibly rain.

It's quite a tricky one.

We'll know that we're gonna get out way of each other when we have to.

We know that we can leave it to the last minute before we switch out the way.

And you know it has to be a mutual trust for the inside shots to sort of try and get that on the move.

We had the card in studio and we used rear projection, so it's a stationary car on.

Then.

We've got projections on the side of the action that they filmed with us not being their screens.

Girl on action and you have to say lines at the right time.

Too much the appropriate background way have to choreograph our moves and dialogue, we are told, accelerate reverse break theme verse speed you've got Lunge forward and then you will break reverse.

You've got London.

So we had all those guys shouting that as we were doing the scene.

So it's quite complicated to do so.

When we were a verse in backwards, I was I think I'm going like that on broadside.

If we reverse in and without, we're definitely like that.

Okay, cool you do whatever you do now follow you three action stuff just seems a bit more full on.

There's a lot more action.

The stakes are high because its potential imminent death, particularly at the end of the scene where we're reversing to edge of a precipice and we, you know, we don't know why it is.

But we could see this does nothing beyond those barriers because going backwards, there's no one driving.

So it's a bit scary.

I don't know.

I think anybody would be in this situation would be.

This kid did it.

I feel like yes thinks she's invincible just because she's got the doctor.

So as much some scared because I've just seen something on reversing back 100 miles an hour.

I always think I'm not gonna die.

Oh my God, what just happened?

That's what I love about playing The doctor is the need for the doctor speed of thought on dhe ability to think in a high energy and chaotic environment.

I don't know Theo, use of the review mirror on gets there in front of the whole time, you know, he's turned in the alien's power back on itself, right?

The beginning of the new series You into celibacy.

Yeah, this doctor's capable of this Doctor's proactive this, you know, when the chips are down and she's up against it, she always finds a solution or improvises.

And that's a classic example of her managing to improvise.

In the moment I was in the front, I had more opportunity to save the day.

But I'm sure if Graham and had been in the front or Ryan or years, they would have done exactly.
