Tonight: The Hungry Earth

The Hungry Earth
Saturday, 22 May 18.15, BBC One

It's 2015 and 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. And when the Doctor, Amy and Rory arrive in a tiny mining village it's not long before they find themselves plunged into a battle against a deadly danger from a bygone age.

Here are Digital Spy's ten teasers for this episode:

1. Amy and Rory are expecting to arrive in Rio when The Doctor mistakenly lands them in a Welsh village in the year 2020. Yes, it's just an excuse to see Amy in a tiny skirt for the next two episodes but let's agree to overlook that.

2. Immediately The Doctor senses that there's something unusual with the ground below them. There's something wrong with the grass, too.

3. Pay attention to the script very early on in this episode. A lot of the lines will have added poignancy after the story is done with.

4. The Doctor loves a big ****** *****.

5. Nasreen Chaudhry (Meera Syal) is heading up a team that has drilled further into the Earth than anyone has before, 21km deep. Unfortunately her drilling has disturbed something below...

6. The Earth is pretty hungry. Ravenous in fact. It consumes Amy and it's still got the munchies!

7. Shameless! Plug! For! Sherlock!

8. The Doctor: "Silence. Absolute silence."

9. When The Doctor comes face to face with a Silurian, she claims to be the last of her species.

10. The Doctor: "Nobody **** today."
