As you probably know, The Sarah Jane Adventures returns this week with the two part story Prisoner of the Judoon - and later in the series, David Tennant joins the show for highly anticipated crossover story The Wedding of Sarah Jane Smith!
Having Tennant appear as the Doctor in one of the spinoff shows is of course pretty marvellous - and also sees the character return to the traditional 25 minute format of (the majority of) the classic series.
The Wedding of Sarah Jane Smith stars Lis Sladen as Sarah Jane, David Tennant as the Doctor and the usual cast of Tommy Knight as adopted son Luke, Daniel Anthony as Clyde Langer, Anjli Mohindra as Rani Chandra. Veteran actor Nigel Havers appears as Sarah's fiance Peter Dalton...
We'll not give too much away until closer to the date - in the meantime, here's a smashing photo of the Doctor and Sarah Jane!
