The BBC will be showing "stings" for the forthcoming anniversary episode The Day of the Doctor tonight, the official site announced earlier today.
Revealing the ident and hashtag that will be used for the story, they will be shown on BBC One immediately before and after Atlantis - the BBC's new fantasy drama - which starts at 8.25pm.
Viewers can also look forward at some point to an all-new trailer that has been specially written and shot for the episode and is currently in post-production. In the meantime, an image has been released from behind the scenes of making the trailer.
The Day of the Doctor will air on Saturday 23rd November.
