The Doctor Who publicity machine has stepped up a gear with the release of new images from Peter Capaldi’s debut as The Doctor.

The episode, Deep Breath, will screen on TV and in cinemas on August 23 and features the highly anticipated entrance of the 12th Doctor. The Doctor appears to have a look of intense foreboding as he dines with companion Clara Oswald.

The dapper Doctor appears to have come face to face with whatever foe he must do battle with in Deep Breath…

Who is it? Well, it’s a closely guarded secret, although The Doctor’s old ally Madame Vastra does appear in Deep Breath.

The return of Doctor Who features on BBC1 on Saturday, August 23.
