A brief trailer for the next Doctor Who special was shown at the end of tonight's BBC One premiere of Planet of the Dead. The trailer confirmed that the next special, the second of four to be shown this year to round off David Tennant's time as the Tenth Doctor, will be called The Waters of Mars. No specific broadcast date was given - it was stated that the episode will be shown later this year.

For viewers in the United Kingdom, David Tennant's fifth video diary is now online.
