With thanks to those who alerted us to this, the BBC Press Office has released a trailer of two of BBC One's biggest shows for Christmas. The first is The Gruffalo, which we're really looking forward to. The second, of course, is Doctor Who: The End Of Time.

The trailer offers a taster of both, and in the case of the latter, we see quite a bit of material that we've not seen before. So there's Lucy Saxon, The Master, the words of The Ood and whatever that gate thing is.

This is, of course, the bit where we stop talking and leave you to enjoy it. So we'll do just that...
