On 13 October, the following important behind-the-scenes events were known to have occurred:
- 1963 - Sydney Newman replies to Donald Wilson's memo of the previous day. He claims to entirely be on Wilson's side, and asserts that he was misled as to Lime Grove's meagre production capabilities. Nevertheless, he acknowledges that they are in a pickle now that he has agreed to Lime Grove on the basis of the misinformation he received. Newman says that he will "do the best [he] can" to get a studio that's capable of producing a story in which the TARDIS travellers are shrunk to miniature size. In the end, however, this story, eventually called Planet of Giants, is postponed even further than Wilson had envisaged in his memo to Newman.
