Doctor Who teaser trailer - spinning Christmas trees!

The teaser trailer for the Doctor Who Christmas special, The Christmas Invasion i sonline (click "WATCH Teaser") ans also showing all over BBC 1.

It' a very short clip and it shows as spinning Christmas tree! It must be the psychotic tree that Russell T Davies mentioned in a previous interview. Funny to me, scary to young children?!

Also online are some photos from the episode, including the evil Father Christmases, looking scary with their brass band instruments.
