Castrovalva (Doctor Who)
Castrovalva is the first serial of the 19th season of the British science fiction television series Doctor Who, which was first broadcast in four twice-weekly parts on BBC1 from 4 to 12 January 1982. It was the first full serial to feature Peter Davison as the Fifth Doctor. The title is a reference to the lithograph Castrovalva by M. C. Escher, which depicts the town Castrovalva in the Abruzzo region, Italy.

In the serial, the alien time traveller the Doctor is led into a trap when his arch-enemy the Master (Anthony Ainley) uses the mathematical abilities of the Doctor's travelling companion Adric (Matthew Waterhouse) to create Castrovalva, a town whose dimensions fold in on itself.
After his regeneration at the end of Logopolis, the Fifth Doctor is still weak, and his companions, Adric, Nyssa, and Tegan take him to his TARDIS. Inside, the Doctor is delirious but asks to be taken to the "Zero Room" that contains Time Lord healing technology to allow him to recover.
Tegan and Nyssa discover a terminal on the TARDIS that describes how to use the machine. They attempt to pilot the TARDIS but find they are travelling rapidly to a preset time and destination, "Event One", the Big Bang, a trap set by the Master. After they are unable to find Adric, the women manage to bring the Doctor to the console room in time for him to jettison a quarter of the TARDIS' mass to propel them back to conventional time. They soon discover that the Zero Room was part of the jettisoned mass, so with the help of Nyssa the Doctor builds a temporary coffin-shaped zero cabinet from the zero room's doors. Tegan discovers information on the town of Castrovalva, an ideal place for the Doctor to recover, and directs the TARDIS there.
In the forest, Nyssa and Tegan have difficulties in transporting the Doctor, and become separated from him; the Doctor is captured by warriors protecting Castrovalva, while the women are forced to climb a rocky cliff to reach its entrance. The Doctor is cared for by Shardovan, a librarian, and the elderly Portreeve, before Nyssa and Tegan arrive. After a night's sleep, they discover strange aspects of Castrovalva; if they go out of the town through any of its exits, they find themselves in a particular plaza in the town, and a tapestry in the Doctor's rooms changes and reflects events of the outside world. The Doctor understands that they are trapped in a "recursive occlusion", and Castrovalva is fake. The Portreeve reveals himself as the Master, and shows them the trapped Adric. The Master has been able to use Adric's mathematical genius to create Castrovalva as well as alter the TARDIS, creating the terminal on the console that led them here. Realising the true nature of Castrovalva's reality, Shardovan swings from a chandelier into the web and destroys it, freeing Adric and causing Castrovalva to fall apart. Seeing all is lost, the Master flees to his TARDIS. The Doctor and his companions flee from the town. The Master appears to be trapped and is unable to escape as the town collapses in on itself. As the time travellers return to the TARDIS, the Doctor indicates that he has fully recovered from his regeneration ordeal.
While he is still disoriented, the Doctor addresses Adric as "Brigadier" and "Jamie", Tegan as "Vicki" and "Jo", mentioning the Ice Warriors and K-9 as if they were in the vicinity, as well as adopting mannerisms or figures of speech characteristic of his four previous incarnations.

The working title for this story was The Visitor. This story was the first story aired which featured Peter Davison as the Fifth Doctor. However, it was the fourth story to be recorded as the original planned debut story, Project Zeta Sigma by John Flanagan and Andrew McCulloch, proved unworkable and a replacement had to be commissioned. John Nathan-Turner took advantage of this to give Davison the chance to have a firm idea of how he wanted to play the role before recording the regeneration story.
Part 1 of this story is notable for being the first episode in Doctor Who history to credit the title character as "The Doctor", rather than "Doctor Who". The credit would remain as "The Doctor" until the series' cancellation in 1989, at the end of Season 26. In the 1996 TV film, no credit was actually given for the Eighth Doctor (although the Seventh Doctor was called the "Old Doctor" in the onscreen credits). For the first season of the 2005 revival, the credit reverted to "Doctor Who". The title became "The Doctor" again in "The Christmas Invasion" at the request of new star David Tennant.
For the final scene, the script called for Adric to look "pallid" as he was still recovering from the effects of imprisonment by the Master. According to the commentary on the DVD, this was accidentally achieved by Matthew Waterhouse, who had a hangover from the night before from drinking too much Campari. Whilst the cameras were filming the Doctor and Tegan in conversation about who landed the TARDIS, Waterhouse was vomiting behind a tree. The other actors continued acting despite it so the take could be used.
For this story, the series was shifted from its traditional Saturday early evening transmission to a twice-weekly (Monday and Tuesday) slot.
In order to keep the Master's disguise hidden, in part 3 the role of the Portreeve was credited to "Neil Toynay", an anagram of "Tony Ainley". Director Fiona Cumming's husband Ian Fraser, later a production manager on Doctor Who, came up with the idea. Michael Sheard had previously appeared in The Ark (1966), The Mind of Evil (1971), Pyramids of Mars (1975) and The Invisible Enemy (1977), and would subsequently appear in Remembrance of the Daleks (1988).
Castrovalva is the name of an early lithograph by the Dutch graphic artist M. C. Escher, and the design of the town in this serial reflects the impossible nature of many of Escher's later works. The story centres on the mathematical principle of recursion, a concept portrayed in much of Escher's artwork. Escher's lithograph depicts a town in Italy atop a steep slope, a setting similar to that of The Curse of Peladon (1972), but there is nothing in the print itself to suggest the paradoxes of this story.
"Event One" appears to be a reference to the Big Bang – the creation of the universe. However, it is repeatedly described in this story as "the creation of the galaxy", which is believed to be a quiet, tranquil coalescing of hydrogen predating the first stars rather than a dramatic cosmic event.
