YOU may have seen these by now, but here are the BBC press launch and BBC America trailers.
Notable moments to look out for:
1) Is the Doctor smiling because he can see up Amy’s pyjama top or bottoms when she is floating in space?
2) Is that super-snazzy spaceship the Hesperus, which River Song mentioned crashing when she met the Doctor in the library?
3) Yes, that really is Spitfires fighting a Dalek saucer with laser guns
4) Some great sonic action
5) What is that noise when the Doctor and Amy put their backs to the wall?
6) The incongruous Hollywood voiceover at the end of the BBC America trail
