NO STRANGER AROUND THESE PARTS...
David Tennant's usual "Production Diaries" return, and will feature 15 minute behind the scenes footage of the cast and crew recording that same season finale.
It also includes information collected from the 14 episode commentaries*, which includes a few nuggets about the production of The Sarah Jane Adventures series 2, which - when they were recorded in May 2008 - was still in the middle of production.
• The production team couldn't find an actor short enough for Kaagh in The Last Sontaran so they had to make a new costume - thereby upping the cost of the episode.
• The actor who played the milkman from Journey's End is to appear in an upcoming episode.
• Catherine Tate wants a part (but not as Donna Noble), as her daughter loves the show.
• David Tennant wants to be the voice of 'Mr. Smith'.
• The biggie! David Tennant was to appear in the opening episode (in a sub-plot which would explain why K9 wasn't appearing in the show) but, at the time of recording the commentary (May 2008), this idea was binned. Julie Gardener states "it could still happen".
Thanks to Den of Geek - who also include a review of the SJA series one boxset, and report rumours about a certain Tom Baker [SPOILERS, perhaps]
*Sadly, there's no Lis Sladen commentary. It's the "School Reunion" fiasco all over again! Haha. No, seriously, she was too busy filming her own show to take part. I'm guessing you'd rather have twelve new SJA episodes than one/two retrospective commentaries?!
