‘Lost’ Doctor Who episode The Tenth Planet part four to get animated regeneration

The key missing episode of the First Doctor's final story is to be resurrected via 'Thetamation' for DVD release later this year


Classic Doctor Who story The Tenth Planet is to have its long-lost fourth episode brought back to life via animation for a new DVD release.


Originally broadcast in 1966, The Tenth Planet is one of the most significant stories in Doctor Who history. As well as introducing viewers to the Cybermen, it was also the last serial to feature First Doctor William Hartnell, and part four contained the Time Lord’s first ever regeneration.

But while the episodes one to three of The Tenth Planet are all safely held in the BBC’s vaults, the fourth went missing during the 1970s. All that currently remains of part four is its soundtrack, some stills and a brief clip of the episode’s regeneration scene (see below).

Speaking at the Gallifrey One convention this weekend, Dan Hall, who commissions the classic Doctor Who DVD range, said: “It’s a real thrill to be bringing such an iconic Doctor Who episode back to life.

“Without the events established in The Tenth Planet episode 4, there would be no Doctor Who as we know it!”

The episode will be reconstructed using Thetamation, an animation technique which involves collaborators from around the world working online and mixing traditional line drawing with cutting edge compositing, editing, special effects and storytelling techniques.

Thetamation was recently used to re-create the missing fourth and fifth episodes of The Reign of Terror, another First Doctor serial, which was released on DVD in January.
