The Tenth Planet (Original Airdate: 8 Oct, 1966)

[Observation room]

BARCLAY: You say you know what this planet is. Well, what is it?

DOCTOR: Well I’m not quite sure, sir. Let me have another look into this instrument.

DYSON [OC]: Zeus 4, Zeus 4, can you hear, over?

BARCLAY: (intercom) Feed the retina scope into the observations room monitor.

CUTLER: Look, Doctor Barclay, let’s just get those boys down.

DOCTOR: General, General, yes, it’s just as I thought. Come and have a look at these land masses.

CUTLER: Land masses? I don’t see. I see what you mean.

DOCTOR: Now, doesn’t that remind you of anything?

CUTLER: Remind? No, I don’t think so.

BEN: Yeah, it looks familiar somehow.

POLLY: Yeah. Hey, Ben, look, that bit looks just like Malaysia!

CUTLER: Nonsense, how could there be?

BARCLAY: This is unbelievable. That’s surely Africa?

DOCTOR: And now, my dear Doctor Barclay, I suggest you look at that piece of paper I gave you.

BARCLAY: He has correctly written down what we have just seen and he did it before we saw it.

CUTLER: It’s a simple confidence trick, that’s all.

BARCLAY: No, I know when he gave me the paper. Now you clearly know something more about the situation. Can you be more explicit?

DOCTOR: Yes, sir, I’m sorry, I’m afraid I can. You see, millions of years ago there was a twin planet to Earth and

CUTLER: Oh, for heaven’s sake!
