production documentation

The production documentation only referred to the project as Doctor Who.

Although the episode features no on-screen title caption, it is referred to in all production documentation as "The Most Special Agent".

The Performing Arts Collection at the Arts Centre, Melbourne, holds a substantial number of costumes, props, photographs and related documents for the production, with the National Film & Sound Archive in Canberra also holding a substantial collection of production documentation and photographs relating to the show.
