This thrilling news has been a long time coming - for years, the new series was completely off limits to the people of Big Finish, until they recently announced spin-off series featuring Kate Stewart and Osgood of the TV series' UNIT and Captain Jack Harkness himself in a new Torchwood continuation. But now - finally - it looks like all kinds of heroes and villains from post-2005 Who can interact with classic characters.
Firstly, the head-lining event is that River Song will be meeting the Eighth Doctor, in a sequel to the Doom Coalition series which will be released next year. Personally, I think Alex Kingston and Paul McGann will make a brilliant pair, as McGann's Doctor is so much like the modern incarnations that he'll be right at home with River.
The inclusion of River into the world of classic Who should be loads of fun - I would particularly like to see the flirtatious River meet her future husband in his first, crotchety, incarnation. And, as Big Finish also have John Barrowman onbaord, why not have a Captain Jack-River Song team-up?
But, wait, that's not all. Also heading his own series will be that favourite Doctor Who character... Winston Churchill! Narrated by the TV show's Ian McNiece, Winnie's adventures will see him meet the Ninth, Tenth and Eleventh Doctors. And Daleks by the look of it.
Bizarrely, The Churchill Years will also feature a guest appearance by Danny Horn, reprising his role of the Scrooge-like Kazran Sardick from 2010's A Christmas Carol. As a character who had such a transformative story arc in his sole television outing, he seems an unlikely returning figure but I'm intrigued to find out why he's back - and teaming up with Churchill.
And that's still not all. The announcement that brings the most fannish thrill to the hearts of whovians is the Classic Doctors, New Monsters series which will see - yep, you guessed it - Doctors Five, Six, Seven and Eight facing foes of the 21st century era. Namely, the Weeping Angels (not quite sure how these silent creatures'll work on audio), the Sycorax (always thought they deserved a second go on the show), the Judoon (their booming voice is well suited to radio drama) and apparently Sontarans from the Time War. Which it seems Big Finish may be able to document now...
I, for one, am very excited for these new adventures - as it suggests such a wealth more to come. Who's to say they can't tempt modern Doctors and companions - even, dare I say it, Christopher Eccleston - to record some full-cast adventures? Or can they get Georgia Moffet onboard to create a spin-off series for the Doctor's daughter, Jenny? Or how about doing that Paternoster Gang spin-off that is such a popular idea? Or what about...
In short, this is exciting news.
