The Star Beast will air on BBC One and BBC iPlayer at 6:30pm, so Whovians can now set their clocks for that time.
The first special will be followed by two more episodes, titled Wild Blue Yonder and The Giggle respectively, with all three instalments seeing beloved stars David Tennant and Catherine Tate returning to the show.
While Tate is once again playing her previous character Donna Noble, Tennant is playing a slightly different Doctor to the Tenth iteration he made iconic between 2005 and 2010.
