The Impossible Planet and The Satan Pit become one feature-length version of the Sanctuary Base 6 story.
The Satan Pit Extended Cut changes how an existing Doctor Who story is assembled. It combines The Impossible Planet and The Satan Pit into a single movie-length edit, returning deleted scenes to the narrative rather than leaving them as separate DVD extras. BBC Studios also identifies previously unseen extended footage. BBC Studios’ description of the extended cut and story.
The story places the Tenth Doctor and Rose Tyler at Sanctuary Base 6, an outpost on a planet orbiting a black hole. Something ancient beneath the surface draws the base’s crew into danger, with the Ood and the Beast part of the encounter.
David Tennant plays the Doctor and Billie Piper plays Rose. The setting gives their arrival an immediate problem of location: the TARDIS has brought them to an isolated working base beside a black hole, where the investigation extends below ground.
The cinema presentation is scheduled for November 23, 2026, with selected encore screenings on November 28. November 23 is Doctor Who Day, marking the date of the series’ first BBC broadcast in 1963. BBC Studios’ description of the extended cut and story.
