10 October (production)

* 1963 - Donald Wilson wrote an extensive memo to Donald Baverstock, Sydney Newman, Joanna Spicer and Richard Levin. He passionately argued for a higher special effects effort than the SFX department had apparently been prepared to give. He also pushed back against the apparent institutional sloth in deciding whether to go beyond the first four episodes. Wilson argued that the Doctor Who production team needed a longer commitment, due to extraordinary lead time necessary to produce the show.
