A never-seen-before test animation for missing Doctor Who story, The Dalek's Master Plan, has been uploaded onto YouTube, and embedded below.
The Dalek's Master Plan is a first Doctor story from 1965-1966. Featuring the most parts of the show in a single story, it is split across 12 episodes, but only 3 remain today. Animators Niel Bushnell and Chris Chatterton, and producer Chris Chapman, put together a test animation for the story. Although it was well received, the project didn't happen. Luckily, they were then commissioned to animate The Ice Warriors.
