Along the way, there are some of our customary, off-topic interludes. But here's the official content...

Big Finish News - it's 'Trailer Central' with all the latest trailers from the Doctor Who Main Range, Torchwood and the Third Doctor. There's also a special feature on The Martian Invasion of Earth, featuring a special preview of the music by Jamie Anderson and an interview with star actor Richard Armitage.

Listeners' Emails - another plunge into the email inbox, with some bonus Facebook content, a surprise (and almost incomprehensible) phone conversation with composer Jamie Robertson - plus the return of the Big Finish Competition. All you have to do to join in is email us at [email protected].

Guest Star Interview - this week, Cicero producer/director Scott Handcock chats to his star actors and Cicero brothers, Samuel Barnett and George Naylor.

Randomoid Selectortron - another corker of a release is selected by 'Ran'. Some entirely random chat also turns out to be really rather entertaining. Seriously.

Latest Releases - a selection of the latest releases for you to enjoy, plus some behind-the-scenes chatter.

Drama Tease - the first fifteen minutes of our latest HG Wells Big Finish Classics release The Martian Invasion of Earth, starring Richard Armitage and Lucy Briggs-Owen.
