Journey to the Centre of the TARDIS (TV story)

Journey to the Centre of the TARDIS was the tenth regular episode of the seventh series of Doctor Who produced by BBC Wales. It was notable for marking the first time the Doctor told Clara Oswald about her multiple lives and deaths.

Synopsis
The TARDIS has crashed, Clara is lost inside, and the Doctor has 30 minutes before his ship explodes!

Plot
Clara Oswald is lost in the depths of the TARDIS which is invaded by intergalactic salvage crew Van Baalen Bros., who want to sell it for scrap. However, the Doctor threatens to destroy the TARDIS by putting it in lockdown and activating the self-destruct if the salvage crew doesn't help him find Clara.

Cast

 * The Doctor - Matt Smith
 * Clara Oswald - Jenna-Louise Coleman
 * Gregor Van Baalen - Ashley Walters
 * Bram Van Baalen - Mark Oliver
 * Tricky - Jahvel Hall
 * Time Zombies - Sarah Louise Madison, Ruari Mears, Paul Kasey

Books

 * The History of the Time War appears to be a book unfolding the history of the Last Great Time War. Clara read the book while in The TARDIS' library. She later implies that the Doctor is mentioned in it.
 * The library also contains the Encyclopedia Gallifreya, which is knowledge in liquid form.

The TARDIS

 * Tricky mistakenly describes the TARDIS as "some kind of escape pod."
 * The TARDIS' sentience is alluded to yet again; and when the salvage team tries to open it, Tricky senses that she seems to "suffer".
 * Amongst its other rooms and chambers, the TARDIS has an observatory with a telescope that appears to be the light chamber from Torchwood Estate. (TV: Tooth and Claw)
 * The swimming pool and library are shown. These are mentioned several times by the Doctor and Amy Pond.
 * The Doctor tells Clara that the TARDIS is not like a cheese grater.
 * The TARDIS display that declares "Engine Status: Overload" also mentions the console room, Eye of Harmony, library, observatory, and Arch-Recon.

Individuals

 * Tricky thinks he's an Android, because of a cruel joke his brothers told him.

Story notes

 * The name of the episode was influenced by the novel Journey to the Centre of the Earth.
 * This is the first televised story to include the word "TARDIS" in its title.
 * This episode aired on Jenna-Louise Coleman's 27th birthday.
 * At seven words long, this episode shares the record for the longest televised story title to date with The Doctor, the Widow and the Wardrobe.
 * Sarah Louise Madison, Ruari Mears and Paul Kasey (Time Zombies) are credited on-screen, but not in Radio Times.
 * This is the first time since the series restarted, that the doctor has closed the Tardis doors from the console, rather than manually shutting them. Something that was the norm in the classic series.

Production errors

 * To create letters as a burned area on Clara's hand, the inscription on the "Big Friendly Button" would need to have raised letters that are hotter than the surrounding metal. When the device is shown, it appears to have etched letters, which would create a burned area on the hand with unburned skin in the shape of the letters.

Continuity

 * The Third Doctor saying, "The TARDIS is dimensionally transcendental" and his companion, Jo, asking "What does that mean?"
