Ten and Donna are gearing up to get back into the TARDIS for a few Doctor Who audio episodes dramas. Tate and Tennant just did an interview for the Big Finish, saying how much they enjoyed working together again.
They are absolutely adorable and funny whenever they are together. This isn't the first time that the dynamic duo have been paired together. They've done comic relief episodes as well as Shakespeare's Much Ado About Nothing.
David Tennant and Catherine Tate will be doing three episodes for Big Finish. The first episode Doctor Who - The Tenth Doctor's Adventures: Technophobia by Matt Fitton. Second episode is Doctor Who - The Tenth Doctor's Adventures: Time Reaver by Jenny T. Colgan. And lastly, Doctor Who - The Tenth Doctor's Adventures: Death and the Queen by James Goss.
Currently, Doctor Who - The Tenth Doctor's Adventures is available for pre-order (U.K. only for pre-order and eventual sales at the moment).
Big Finish has also done audio-books with Alex Kingston's River Song, John Hurts' War Doctor and Jemma Redgrave leading the forces of UNIT.
