Picture the scene. It is late 1979. Tom Baker is freezing cold, soaking wet, and trying desperately to learn how to punt down the River Cam in Cambridge. He keeps falling in. Nearby, local college porters stand ready with warm blankets and brandy. This chaotic location shoot was supposed to be the glorious crowning achievement of Doctor Who season 17—a six-part sci-fi epic titled Shada, written by none other than Douglas Adams.
Instead, it became television history's most famous casualty of industrial action.
If you've ever wondered how a routine labor dispute at the BBC completely torpedoed a brilliant script by the creator of The Hitchhiker's Guide to the Galaxy, the reality is messy, frustrating, and entirely fascinating. Let's look at what actually happened behind the scenes when a union lockout turned a television masterpiece into a phantom.
The Cambridge Chaos That Started It All
Douglas Adams was working as the show's script editor while also wrestling with his own rising literary fame. He decided to set a whimsical, highly clever story right in his old university stomping ground. The plot involved a retired Time Lord hiding out as a Cambridge professor, a mad scientist wanting to steal the secrets of a galactic prison planet, and plenty of witty dialogue.
Location filming went ahead in October 1979. The crew captured iconic footage on the historic streets of Cambridge. Tom Baker chased a floating villainous sphere while riding a bicycle. It looked incredible on paper and on film.
Then the cast and crew packed their bags, returned to London, and walked straight into a brick wall.
Locked Doors and Chain-Linked Studios
Production assistants and design crew members arrived at the BBC Television Centre for their scheduled studio block only to find the doors padlocked and chained. Technicians were on a prolonged strike.
Les McCallum, a design assistant on the project, recalled returning from lunch to find the studios completely shut down. The union dispute dragged on for weeks. By the time the strike finally settled, the studio time originally booked for Shada had vanished. The BBC had already reassigned those slots to higher-priority Christmas programming.
Only about half of the serial was ever filmed. The remaining indoor scenes, crucial confrontations, and dramatic payoffs were left unrecorded.
Fans waited. And waited.
Marcus Hearn, editor of Doctor Who Magazine, recalled hearing firsthand stories from his father—who worked as a porter at Clare College during the chaotic shoot—about Baker's freezing antics on the river. Hearn later waited eagerly for the episodes to broadcast, only to realize they were never coming. The unfinished footage mutated from a delayed broadcast into an absolute myth.
How the Phantom Came Back to Life
For decades, Shada sat in the archive as a collection of disjointed pieces: a pile of scripts, Cambridge street tapes, and incomplete audio recordings. But the Whoniverse refused to let it die quietly.
Over the years, the BBC tried multiple salvage operations. In 1992, they released a cobbled-together VHS version featuring linking narration by Tom Baker. Years later, they transformed it into an animated webcast starring Paul McGann as the Eighth Doctor. Finally, in 2017, the BBC did what fans thought was impossible. They brought back the original surviving cast members—including an aging Tom Baker—to record new dialogue, paired it with fresh animation to fill the missing gaps, and gave the story a proper digital release.
A strike stopped the cameras in 1979, but it took nearly forty years for the TARDIS to finish the trip.
If you want to experience Shada today, track down the 2017 animated completion or pick up Gareth Roberts' expanded novelisation based on Adams' original notes. Just remember to pour yourself a glass of brandy while you watch it, in honor of the freezing crew on the River Cam.
