The Invasion

The Invasion is a serial in the British science fiction television series Doctor Who, which was first broadcast in eight weekly parts from 2 November to 21 December 1968. It is the first now-incomplete Doctor Who serial to be released with full-length animated reconstructions of its missing episodes.

After the newly reformed TARDIS evades a missile fired at it from the far side of the moon, the Doctor, Jamie and Zoe arrive in late twentieth-century London. However the TARDIS's visual stabiliser has become damaged, rendering it invisible. In order to have it repaired, they set out to find Professor Travers (of The Abominable Snowmen and The Web of Fear) and ask for his assistance. When they arrive, they find that he has left for America, leaving his home in the care of Isobel Watkins and her scientist uncle, Professor Watkins. She explains that her uncle has disappeared, after he worked on an invention for International Electromatics. The Doctor and Jamie go to IE's head office in London to investigate.

As with many serials from the Troughton era, a complete version of The Invasion does not exist in the BBC's archives, with Episodes 1 and 4 having been lost. However, their soundtracks survive, recorded off-air by fans at home.

The story was released on BBC Video in 1993, with the missing Episodes One and Four summarised on-screen by Nicholas Courtney. This was the first incomplete story to be released on BBC Video.

The soundtracks for The Invasion and The Tenth Planet along with a bonus disc, The Origins of the Cybermen, an audio essay by David Banks, were released in a collector's tin called Doctor Who: Cybermen.

In June 2006, the BBC announced that the animation studio Cosgrove Hall, who previously created the webcast Scream of the Shalka, had produced full-length animated versions of the two missing episodes. These episodes, along with newly remastered copies of the rest of the serial, were released on DVD on 6 November 2006.

The DVD release included the documentary Evolution of the Invasion produced by John Kelly and featuring interviews with a number of the cast and crew.
