The BBC's official Doctor Who website has been updated with two new promotional images and a preview clip taken from the upcoming second Doctor Who special episode for 2009, The Waters of Mars, which stars David Tennant as the Doctor and Lindsay Duncan as Adelaide Brooke. The clip runs for 53 seconds and can be viewed on this site below.

A promotional trailer for other BBC programmes coming this Autumn can be seen with the promotional images for the episode here on Digital Spy. The Waters of Mars is expected to air in November.
