A new trailer for Series Four is now available to view online at the official website's home page as well as on the BBC's YouTube channel.
Lasting 39 seconds and given from the perspective of new companion Donna Noble, it includes three of the monsters that will be appearing in the new series.
UK TV licence restrictions may mean the trailer cannot be viewed by overseas visitors to the sites.
(NB: While hovering your mouse over the official website home page, a box currently pops up with the following text: "Watch the second new trailer tonight at 8.30pm, BBC One and online." However, this does not tally with today's schedule for BBC One.)
