Production
The story had the working title Doctor Who and Tanni, which was the original name for Vicki. The 1973 Radio Times 10th anniversary special called the story The Powerful Enemy, as it titled all the early stories by the title of the first episode.
When shooting Vicki's Sand Beast, Jacqueline Hill suffered shock and a sore face because the effects gun had more power than she was expecting.
To preserve the mystery of its true identity, Koquillion was originally credited as being played by "Sydney Wilson" — a name made up by the production team in tribute to two of the creators of Doctor Who, Sydney Newman and Donald Wilson. This was the first instance of an alias being used in the credits in order to conceal a plot twist in Doctor Who; the practice would be employed later on to conceal the appearance of villains Davros and the Master.
