Mission to the Unknown (webcast)

Mission to the Unknown was a recreation of the missing second serial of season 3 of Doctor Who. Carefully remade by students, graduates and staff at the University of Central Lancashire on the basis of whatever scripts and production photos from the original lost version could be located, it was released as a webcast on YouTube on 9 October 2019, 54 years after it first aired, with original production values of the 60s.

It is the only Doctor Who television story not to feature the Doctor, any of their companions, or the TARDIS. This story was also notable for being the only one-part serial in the classic era.

Summary
On the planet Kembel, Space Security Service agent Marc Cory is investigating a recent sighting of a Dalek spaceship. His suspicion that the creatures may have established a base proves well-founded. He learns of a plot by the Daleks to invade and destroy the Solar System, but he is discovered and exterminated. The Daleks and their allies vow to conquer the universe, beginning with the planet Earth.

Story notes

 * This one-episode recreation was made because the original story does not exist in the BBC Archives.
 * In a Q&A session during filming of the University of Central Lancashire's remake of Mission to the Unknown, Edward de Souza stated that when they shot the original episode "None of us thought that it would mean anything at all. It was just another episode of Doctor Who...it didn't really impinge on us at the time; it wasn't much more than a week's work". He also remarked that he watched the original episode with his son sitting on his knee and that "when it came to the moment when the Dalek zapped me, he stiffened and spun round to make quite sure I was still alive."
