10 teasers for Doctor Who's 'Journey To The Centre Of The TARDIS'

When the TARDIS is pulled aboard a junk ship as "the salvage of a lifetime", the Doctor (Matt Smith) and Clara (Jenna-Louise Coleman) end up separated, with the Time Lord's young companion lost in the bowels of the ship...

To save the girl and his craft, the Doctor and the junking crew - two men and their robot co-worker - will have to travel to the very heart of the TARDIS. But all manner of secrets - and all kinds of terrors - lurk within...

1. This ain't no bluff - you *will* see the heart of the TARDIS.

2. "That's properly bonkers!"

3. Expect many nods to the past - all the way back to 'An Unearthly Child'.

4. "The TARDIS will get huffy if you mess."

5. It's a timey-wimey one this week - the plot twists and turns almost as much as the TARDIS interior.

6. "I'd explain if I had some charts and a board pen."

7. The Doctor and Clara take a leap of faith...

8. "Don't get into a spaceship with a madman!"

9. Some people are an open book - some people are most definitely not.

10. "I think I'm more scared of you right now than anything else on that TARDIS."

Doctor Who continues on BBC One on Saturday (April 27) at 6.30pm
