Excuse the muddle. Creative disarray, you know.
Modern viewers of Doctor Who breathe a sigh of relief when they reach the Jon Pertwee era, if only because the Third Doctor’s run marks the end of the “missing episodes” that plagued Hartnell and Troughton’s time as the Doctor. It’s all there on film, every moment of the Third through the Eighth Doctor’s exploits. Except, that is, for Douglas Adams’ “Shada” (Story Production Code 5M), the six-part finale for Season Seventeen that was partially filmed but never completed or broadcast due to industrial action at the BBC.
All the story’s location shooting in and around Cambridge had taken place and the first of three studio sessions was in the proverbial can when a strike stopped all filming. The knock-on effects of multiple shows scrambling for studio space and technical crews once work resumed clearly revealed Doctor Who‘s place in the BBC hierarchy at the time: dead last. Other shows received preference for scarce resources, and the decision was ultimately made to cancel the production entirely rather than spend money storing props and sets and keeping options on actors with other jobs to get on with.
As the swan song for both producer Graham Williams and writer and script editor Douglas Adams, “Shada” would have been quite an achievement on the strength of the extant footage alone: between an inventive (if slightly incomprehensible) story and a superlative guest cast, this tale about a secret Time Lord prison and a megalomaniacal scheme to absorb every mind in the universe into one giant consciousness hints at being as good as anything in Season Seventeen, and potentially one of the best stories in the series to date. To that end, several efforts were made to complete “Shada,” including a version in 1992 with linking narration by Tom Baker between existing footage, an audio play in 2003 (with Paul McGann’s Eight Doctor subbing in for Baker’s Fourth Doctor), and a full animated reconstruction of the unfilmed scenes in 2017 featuring the original cast, which forms the fullest version of the story.
“Shada” sets up in Cambridge, where the Doctor’s old friend and fellow Time Lord, Professor Chronotis (Denis Carey), keeps quarters at (fictional) St. Cedd’s College. Despite having a name even Terry Nation might have blanched at, Chronotis possesses a warmth in his bumbling absent-mindedness, suggesting both age and wisdom in equal measure and played brilliantly by Carey, who gamely takes on all of Adams’ dialogue. He invites a junior teacher, Chris Parsons (Daniel Hill), to borrow several books, one of which just happens to be radioactive, capable of reversing time, and allows access to the long-forgotten prison of the Time Lords—Shada. Worse still, the book is being sought by the evil mastermind Skagra (Christopher Neame), who strides out of his invisible spaceship in his disco best, with a carpet bag full of voices. (Yes, this was made in 1979, in case there were any doubt…)
